Yandex Reverse Image Search
Reverse Image Search or Reverse Photo Search is a very important feature to find out images or original images sourced from the web. Here image, instead of text, is used to find out the expected result.
Though finding out similar kinds of images is very hard on the internet but this duplicate photo search helps people to search those images simply by uploading an image as well as inserting an image URL. Search engines such as Google, Yandex provide image reverse search facilities to the user.
It is a content-based image search technique, where there is no need to remember or guess any type of keyword to find out expected results/images. It works like an autopilot. This tool provides results so fast and accurate, if there is no exact result of “the search” then it tracks similar kinds of images from the search engine for “the seeker”. It also redirects the user to a specific page when a user clicks on ‘checked images’ with their preferred search engine.
There are a lot of companies that have developed their database to search images directly from their records. But there are trillions of pictures available on the internet; So it is not possible to store all images in a single database. Well, there are some big guns who developed this tool just like google image search. Yandex and bing have also developed a big database to find related images from the internet. Images searched by google are very close to your required picture but Yandex and bing sometimes show irrelevant images.
