To find duplicate images, search engines use the search by image technique. This makes it easy to search for what you are looking for. This feature uses the image data set to its fullest. Previously, images were visually blank to the search engine, only tags, names title descriptions, their textual pieces of information were processable by the search engine and hence all visual data was of no use.
What is Search by Image?
Photo search is a technique used by many renowned search engines to help with the searching process. The main difference between reverse image search and common search is the difference in input and output forms. Instead of words, people enter images to search for what they want. This means a visual search is performed and results are also enlisted based upon the visual similarities.
This search by image feature has revolutionized the searching process making drastic advancements in the field of digital marketing and business.

Search by image was also possible because of this advancement. Even modern SEO was updated by the inclusion of images in the input section and the display of the reverse image as output.
Program crawls through the image database to find results against the image that the user has entered. It compares visual data, alongside the tags and titles of the input image. It then displays the most similar images in the search results. From there you can see if there are exact duplicates of the images present on the internet.
