We are going to use picture fingerprints to detect similar images. This technique is often referred to as "perceptual image hash" or simple "picture hash".What is picture fingerprint/Picture hash
A picture hash is the process of detecting the contents of a picture and then establishing a unique value for the picture based on the contents of the test.
For example, look at the picture at the top of this article. Given a picture as input, appl
Most of the time, I don't know what keywords I should use to search for the desired image, but often "I want an image like this ." It is difficult for traditional image search engines to meet such requirements. Similar image search engines have emerged.

Search for similar images
Similar image search refers to how to calculate the similarity between two images. The key technology here is "perceptual hash algorithm ), it generates a "fingerprint" (fingerprint) string for each image, and then compares the fingerprints of different images. The closer the result is, the more similar the image is.
