How to Search for Images With Reverse Image Search

Have you heard of reverse image search before? If you have never heard of it before then do not worry because you are not alone. Some people do not even know that this exists. Perhaps because of doing research, you have come across the term ‘reverse image search.’ You would like to know more about it and you have come to the right place.

What Is Reverse Image Search?

What Is Reverse Image Search

This is basically known as CBIR or Content Based Image Retrieval. This is a type of technique wherein an image is connected to a content. The sample image will be used in order to retrieve content and information about a certain topic. This means that you do not need to use a lot of terms like with normal queries to gain information about what you are searching for.

This can be beneficial if you are trying to eliminate some keywords that will not work when searching for products online. If you have a product that you are trying to sell, using the reverse image search will allow you to know what keywords are not needed anymore.

With the use of a reverse image search, you can get the following:

  • Figure out content that is closely related to the given sample image.
  • Get to know how popular an image is.
  • Find versions of the image that has been manipulated and derived in order to be used for other products or tasks.
  • You can also locate the current destination of the image.
  • It will give you the ability to search for the same image but with a higher resolution.

Just imagine if you have uploaded a picture that you have taken for your website. With the use of reverse image search, you can figure out if there are other websites that have stolen your image and are using it for your own. You can then report the website because you have rights to the images. If in case your original image is used but it has been changed a bit, you can still use the reverse image search to locate where those images are being used.

Some Algorithms Used for Reverse Image Search

There are some algorithms that are being used in order to make reverse image search possible. Some of these things include the following:

  1. Scale Invariant Feature Transform – This works by checking out the local features of the images so that they will be detected easily. This was started in the year 1999 by David Lowe. This algorithm can be used provided that the features that are being looked for are still easy to detect and are not manipulated to resemble other images instead.
  2. Vocabulary Tree – This is also known as Bag-of-words. Basically, an image that is being searched for will be treated as words. This means that each feature of the image will be transformed in word form. The image that will be used with this algorithm has to be well defined. It has to pass three steps namely: feature detection, feature description and codebook generation. Once the three steps have been passed, this type of algorithm will be used well.
  3. Maximally Stable Extremal Regions – This works by checking out the correlation of a certain image with other images that are similar to it. This is also known as blob detection. This can take a long time depending on the number of similar images to the one that you have uploaded for checking.
