Search by image in Yandex. Analysis of media content in Yandex. Google Smart Image Search

Neural networks firmly entered into our lives. IN this moment, based on them in World Wide Web functioning great amount services of different purposes that simplify the search and processing of information. Some of the most significant achievements in the field artificial intelligence, today, are image recognizers from Google and Yandex, the desktop versions of which many users are familiar with. But few people are aware that search similar pictures with their help you can perform not only on a PC, but also on a smartphone. And this may be necessary at a time when there is no computer at hand. Therefore, in this article we will consider all the ways to search by image from a phone using Yandex and Google. Also, in a separate section we will consider the principle of operation of such services, which will allow you to general outline understand which images it is advisable to upload to search for similar ones.

I think many people are familiar with this page. This is how the desktop version of the service works to find similar Google images. How it works mobile version- Let's look at it in more detail in the article.

If we talk about the principle of their operation, it is quite simple - you provide an image as input (it can either be downloaded from your phone or found in search results). The recognizer tries to find an image that is as similar as possible to the one provided by the user. This implies the purpose of the service: quick search similar images. If you recline detailed descriptions methods of filtering, ranking images and training AI, then the stages of image recognition in general terms look something like this:


One of the main stages of recognizing complex pictures is classification by range. An example is presented in the figure + graph of the process of analyzing this image by the classifier.

To understand the final stage, consider the following example. Let’s say that in the process of logical processing, the recognizer concluded that 80% of the image provided by the user is similar to the object “human face”. Let the classifier, as a result of sampling and self-training, obtain ideas about the main features of this object- two eyes, two ears, nose, lips, etc. Then he begins to identify the so-called “weight” of each feature in the image. Let’s say that based on the “presence of two eyes” feature, the picture is in the range 0.7 based on the “presence of a nose” in the interval 0.5. Having received a number of such classifier results, the recognizer determines whether the face is actually depicted or whether the processor made a mistake.

By the way, the boundaries of these stages are quite arbitrary. Sometimes two steps are enough to understand what is shown in the picture and find similar results, or even one step. It all depends on the complexity of the image provided.

Ways to search for similar images on your phone using Yandex and Google

So, there are the following ways to search for similar images in the above services from smartphones:

  • Using the Google Goggles application;
  • Search for similar pictures using the Kate Mobile application.

Yandex:

  • Standard method;
  • Using "Kate Mobile".

Let's look at these solutions in more detail.

Search by image from an Android phone in Google

We use the Google Goggles application:

So, to find a similar image on Google using this method, you need:

Google Goggles did an excellent job of identifying what was shown in the picture and finding similar images in Google Image.

Search for similar photos using "Kate Mobile"

This method also does not have any pitfalls; everything is quite simple. But to use it, you must have a VKontakte profile. So:

How to search by photo via smartphone in Yandex

Standard way:

This solution is extremely easy to implement. To implement it, you don’t need third-party programs; a service for searching similar images from Yandex is enough:


Using the Kate Mobile app

This method is similar to that used when using this program to search for similar images on Google, therefore we perform the first four steps in exactly the same way as indicated in this solution. In the fifth step, we select the service not “Google”, but “Yandex”.

Conclusion

The article examined the principle of operation of services for searching for similar images, and also showed algorithms for their use on the phone. In fact, it is preferable, of course, to use Google Image search. Since the AI ​​on which the service operates, relative to the Yandex recognizer, has a much larger number of metric characteristics used in filtering and processing images. And therefore, the final results will be more accurate.

Search by picture, image, photo in Yandex and Google. Welcome to the pages of the Coolinet website. Today in this article we’ll talk about how you can quickly find the desired picture, image or photograph, as well as all similar images with the searched one and all the information on it in the Yandex and Google search engines. We’ll also see how to find an image, for example, of a product of interest.

Why might you need to search by picture, image or photo? Checking the image for uniqueness, searching for the author, searching for the image for further work with it.

How to find by picture, image or photo in Yandex.

Let's say you need to quickly find an image. For these purposes, there is a tab on the main page of the Yandex browser, when you click on it, you can search by image. Just go ahead and click on it.

We get to a page that already has a selection of pictures and photographs on topics.

You can choose a picture from the suggested topics. Let's move, for example, to the “Water World” section.

Here are collected all the images related to the sea, ocean, marine life, coral reefs and so on. We can set the parameters of the image we need. For example, by size, set what kind of picture, we need large, medium or small.

You can specify exact dimensions, let’s say we need an image of “Water World” measuring 1000 by 800, specify the dimensions and get all the images that fit the size we are interested in.

The parameter settings are quite wide; for example, you can find an image by setting the orientation, horizontal, vertical or square. You can customize the image type, for example, we need pictures on a white background. The Yandex pictures service will accordingly select all the images on the topic we have chosen on a white background.

Or, for example, we need to find a picture and a drawing on a topic, no question, click on the “Drawings and Drawings” tab and we get all kinds of images that fit this criterion.

You can also set the color of the image you are interested in, for example, we need “Blue,” set it and get all the pictures available in Yandex with a blue background.

You can select the image file format from the most common resolutions: JPEG, PNG, GIF. You can, which is very convenient, set search parameters for a product in the pictures. “Water World” cannot be purchased, so it is not suitable as an example.

For example, we want to look at pictures of sneakers and if we like something, we want to buy it.

Go to the “Sneakers” section, click the “Product” tab and get the images of sneakers we need, which have a small icon in the lower left corner.

By clicking on the photo, we will see the price and in which store the shoes you like can be purchased, that is, a link to the website of the seller of this product.

Not today, Yandex has implemented another very convenient search by image. You need to copy the image address. This is done like this: right-click on the picture and select copy address. Then we paste this address into the field and get the search result. Or upload the file from your computer.

Here is the result.

How to find by picture, image or photo on Google.

Searching by image in Google is very similar to searching in Yandex. Let's take a closer look at how it works. If we need to find, using an image in the Google search engine, we need to do the following steps. We go to the main page of the search engine using the link. Or click on the “Images” tab on the Google main page.

A camera icon will appear in the search bar. Click and the following input form will appear in front of us.

There are also two options to search by link or upload an image. Let's try the first method. Copy the image link. You can do this by right-clicking on the image and selecting “Copy image address.” For example, we need to find a picture of a shark and we have the address of this image. The address will look something like this.

It is also possible to change the search parameters: size, color, pattern type, and so on.

Now let's look at the second search option. Go to the “Upload file” tab. A window will open for selecting an image on our computer.

Click on the image file and Google will find the image we are interested in through its search engine. And just like in the first case, it will offer similar images.

Addition, extension for more convenient search.

For those who use the Firefox and Chrome browser for even greater convenience and a faster way to search by picture, image and photo. You can download and install the special extension Google Search by Image.

More services for searching by image, image, photo.

TinEye service

TinEye search service website http://tineye.com/

Let's try to find a picture through it. The principle is the same as that of Yandex and Google. For example, let's find a picture and a photo of a mushroom. Also, use the right mouse button to copy the image address, which is how it turned out in this case.

Paste it into the search field and click find. We get all the images related to ours.

Moreover, you can track on which sites this picture is still found.

That’s actually all I wanted to talk about today in this post.

The Yandex search engine offers us not only information search services, but also other services that are in one way or another related to search services. This is how a photo search is performed in Yandex, where a special section has been created for this. It contains a gigantic database of tens and hundreds of millions of images, among which there will always be suitable results. Let's see what happens in the Yandex.Images service.

Searching for images using Yandex

Recently, mobile devices have begun to be used almost more often than laptops and desktop PCs. Therefore, we will divide our brief review into two parts. In the first part we will tell you how to search for photos in Yandex using a computer, and in the second part we will move on to smartphones and tablets.

Search by photo from computer

In order to get started, we need a browser - absolutely any one. We go to the main page of Yandex, click on the “Pictures” tab, go to the image search engine. There are three search options available to us here:

  • By keywords;
  • By image address;
  • Based on the uploaded image.

In order to upload a photo to the photo search in Yandex, you need to click on the icon with the image of a camera. A double form will open in front of us - in its right half the URL of the image that will be searched is indicated, and in the left half photos are loaded from the hard drive. After specifying the URL or uploading a photo, the system will find us similar images.

Search by photo from your phone

In order to search in Yandex by photo from your phone, you should use any mobile browser that can open full versions of sites, and not their mobile versions. For example, this could be the Google Chrome browser. Check the box in the settings, go to the Yandex main page, go to the “Pictures” tab. Here we will see the same interface that was visible from the computer. We click on the camera icon, indicate the URL of the photo in the form or upload an image from your phone, and wait for the search results to display.

But there is another way, a simpler one - it is to use the original browser from Yandex. Download it from the application store and launch it - the main page of the search engine will be displayed on the screen. Below, under the search bar, you will see the familiar camera symbol. Click on it and see a window with the camera running. Now you can take a picture of any object and search for it.

In the camera window you will see a symbol to go to the gallery. By clicking on it, you will be taken to the list of recent documents. Here you can select any photo or image saved in the internal memory of the phone and search it. Thus, using applications from Yandex is much more convenient than using some third-party browsers for searching.

Searching for photos from your phone is not as difficult a task as it might seem. To reveal all the aspects of this process, we will try to outline what to do if you have the original image on your smartphone and if you want to find something related to the image found on the Internet.
In the second option, there are not so many solutions to the problem, but as long as we have our beloved Google, there is nothing to be afraid of.

As easy as pie

So you are interested in a photograph in some article and want to know more about it. If you haven't yet turned to your favorite browser and use the one built into Facebook, Twitter or something else, now is the time to turn to Chrome, Firefox, Dolphin or any other option that suits you. Having opened the link in the browser, you long tap to select the image you are interested in and open it in a new tab (this option will appear in the context menu that appears, here we also see the option to quickly save the image or immediately start searching for it using Google)

When you see just one image on the page, all you have to do is copy the link to it and consider that half the work is already done.

Open a new tab and go to the Google start page. Here we are interested in the “Pictures” section. Once you go to it, all you have to do is paste the previously copied link to the image into the search bar. Click “Search” and enjoy the results. As a rule, among the truly useful information, unnecessary information also appears. You can refine your search using special filters, but they are not available in the mobile version of the site, so click the “menu” button and check the box next to the “full version” line. Here you can set all the parameters you are interested in: size, type, time, etc.

An equally interesting option is to select an image close to the one you are interested in and follow the “similar” link.

Now let’s consider a situation in which the picture is saved on your smartphone (by the way, you can also save it from the browser if fiddling with copying links seems difficult to you)

We go back to the Google start page and the “Images” tab, but now we select the “Upload File” tab. When you click on it, you will have access to your gallery. Having selected the desired photo, repeat the steps from the previous paragraphs and again you will surely find the one you need.


Applications to help

Now let's look at other ways to search for information using photos from a smartphone. For this we do not need a browser, but we will need third-party applications that will have to be installed in advance.

Google Googles(Android) is perhaps the most famous application of this kind. It hasn't received updates for a long time, but it's still working. Managing it is extremely simple: launch the camera in the application, point it at the object of interest, and take a photo. In a few seconds you will already have all the available information on the object of interest. Admittedly, this method works best with well-known objects: trademarks, landmarks, works of art, etc. Here you can read barcodes and translate text, even solve Sudoku.

CamFind(Android, iOS) - works approximately the same, but is designed mainly for searching for all kinds of products, and can even help you find online stores where they are sold. But it also easily finds related and simply similar images, saves the search results that interest you to your favorites and allows you to quickly share them. There is a code scanner, recognition of famous places and even voice control. You can search from the gallery and from the camera.


Specialized services

But that is not all. If you don’t have time to install third-party applications, and fiddling with tabs in the browser is tiring, you can turn to the corresponding service, the sole purpose of which is to search for images. Tineye was and remains the best in its class. Here you can also upload an existing image or insert a link to it into the search bar (read above for how to get the link you are interested in). The service finds copies of the image you uploaded and links to the resources where they appeared. Alas, everything works only if it is 100% similar. The service has another interesting feature - working with flowers. That is, you can upload an image that Tineye will analyze, select key colors in it and find you pictures in the same color palette or, conversely, select images based on given colors.

So, these are the three simplest and most universal ways to search for any images and information on the Web when you only have one picture on hand. And if not all, then at least one of them will definitely lead you to success.

Hello, friends! In this article I will tell you about how image search works in Google and Yandex search engines. There has always been a search for images in search engines, but it worked using words that could be found in the text next to the desired image on those web pages where the picture we are interested in is present, or words specified in the image attributes. In other words, such a search was not always accurate, since the image we were interested in was not visible to the search engine, and only the words we entered into the search string were determined.

In this regard, before the advent of the image search option, it was not possible to find the original of any picture, having only a copy in poor quality and low resolution, or, for example, you saw an image of a person in the news feed on a social network , and you would like to know who he is. And this is where the image search function, which is most convenient for such purposes, comes to our aid. This function exists in Google and Yandex search engines - the two most popular search engines in Russia (A little more than 50% of the percentage is on Yandex, and about 40% on Google).

To clearly examine the principle of operation of this function, let’s consider it using examples from both search engines.

How does Google photo search work?

In order to start searching by image, go to the images section on the search engine’s website.

We will have two options for further actions: insert a URL link to an image from the Internet, or upload an image from your computer.

In the first case, we need to select the image we are interested in and copy its address. To do this, you need to right-click on the image and select the “Copy image URL” option, and then paste it into the search bar using the image link.

If you upload your image, click on the appropriate tab and select the file we need in Explorer.

There is an even easier way to search by images, available for those using the Google Chrome browser. To search for an image, simply right-click on the image and select the option “Find image (Google)” or “Find this image on Google.”

Since we used a painting to search, having found images on websites, Google automatically gave a name to the subject of our interest. The search results included similar images of varying quality and resolution, as well as links to various sites where a description of the painting was given. Everything is the same as when searching with words, only in this case you used an image, for example, if you need the same picture, but in a higher resolution, you just need to click on the “Larger” or “Similar Images” link and in front of you What you are looking for will appear.

Search by image files in Yandex

Yandex launched an image search function relatively recently. Their way of searching for images is mechanically different from Google's, but they are very similar in appearance. The search mechanics are that the search engine “breaks” the searched image into visual words, i.e. areas in the image where color, brightness, contrast and others change, and then uses these visual words to search the image database.

And only then those in which these visual words are in the same order as in the original uploaded picture are selected. Using this system in practice, you will not notice any special differences from the actions that we did using Google.

Go to pictures in Yandex and click on the camera with a magnifying glass.

In the same way as in the instructions for searching on Google, copy the URL of the image.

Paste it into the input field and click "Find".

Ready! Here is what we were looking for, as can be seen from the screenshot, the results displayed in Yandex are somewhat different from the one Google uses. Yandex allows us to immediately select the image resolution in pixels, but this is where the difference ends and the search results are then presented in the same form as when using Google - Other image sizes - Similar images - Sites where the searched image is found. A small addition from Google is that the first link before similar images will, if possible, be a link to Wikipedia, and only then other sites.

Dear readers, this completes our introduction to image search in Google and Yandex. Having an understanding of the capabilities of search engines, I hope working and searching the Internet will become much easier for you.
