What library in HTML5 should be used to scan an image and find similarity with the image in the database?

Question

Pattern recognition

Case: the user opens a certain site in the browser, then scans the brand logo, and if it is in the database, a video clip is displayed.
What library can be used for such purposes?

Answer 1

There is Tensorflow.js , but this is not a task that is done "on the knee"

Answer 2

In-Browser Object Detection Using Tensorflow.js

Answer 3

Since the author of the question did not specify what exactly is meant by comparing images, I would venture to suggest that a perceptual hash is what is needed. There is a recent article that reveals its meaning: "Looks similar." How perceptual hash works .
A big plus is that you do not need to use machine learning. Everything works simply, quite reliably and does not consume a lot of resources. That is, easier than Tensorflow.
The database of logos is scanned and entered into the database, for example,
Brand | Hash
Comparison of hashes - using Hamming distance. The smaller it is, the closer it is to the original.
