Job description
The subject of the order is to create a mechanism that will be able to index thousands of photos so that you can search for similar photos at a very high level of detail.
The photos to be compared will be those of coins and banknotes, which for most photo comparison algorithms are almost always very similar to each other.
An example of a mobile application that has this functionality: https://coinoscope.com/
The script should be able to index the indicated photo (whether from our database or uploaded by the user).
Input data: binary data of the photo or base64.
Output: a hash, which you will then be able to quickly compare in the database with other hashes and easily find similar photos.
There are several solutions available on GitHub that use neural networks to find similarities, but none of them with default settings do the job. For example: https://github.com/idealo/imagededup
