You already know about the way of giving some letters as the input in order to find matching results. In fact, you do it every single day when you want to search for something on the internet. What would happen if you want to search for something, but you only have a set of images instead of words? For example, you might have a picture of a celebrity and you would want to know her name. The reverse image search can come for your survival in that kind of a situation. This article will let you know about what reverse image search is and what you can do with it.
What exactly is reverse image search?
Reverse image search is all about uploading a specific image instead of a search keyword. As mentioned in the previous example, you will be able to upload an image and get more information about the objects or individuals that are on it. You can also point out the URL to the image instead of uploading it to initiate the search. It is simply powered by a content based image retrieval query.
What factors influence reverse image search?
Reverse image search is influenced by many different factors. For example, some reverse image search engines use colors in order to locate the results. They have the ability to create a color histogram and then compare it with other images that are stored in the directory. If there is a noticeable match between two histograms, the respective image will be fetched and displayed on your internet browser. Reverse image search would scan the image that you give as the input. Therefore, it would scan the textures of the image as well.
In fact, the texture information will be transformed into 2D grey graphs, which can be used to compare and search for matching results. The shape of the image is another determining factor in reverse image search. Apart from these key factors, reverse image search uses a specific mathematical algorithm to compare the input images along with the ones that are stored in directory.
When should you use reverse image search?
You will be able to use reverse image search in a clever manner. For example, you would come across a scenario similar to the one that was mentioned in the introduction. In that kind of a situation, reverse image search would be extremely helpful. It can also help the designers and photographers to make their lives easy. In fact, they will be able to use this technology in order to get new ideas for their designs, analyze the popularity of work and figure out plagiarism. They just need to upload a design or a photograph to the search engine and they will be able to know whether it has been published or not within a couple of seconds. When somebody blabbers that you are using a fake photograph, you can use the reverse image search to bring truth into limelight.
On the other hand, you will be able to use reverse image search in order to figure out the real author of a photograph. Sometimes, you would need higher resolution versions of images that you have. You can use reverse image search engines in such instances as well. Leading search engines such as Google will assist you to find them within a couple of seconds with the help of available filters.
