Which tool to choose for image search?

Question

linux

There is a database of 5 million jpg-pictures with people (in 1 picture there may be more than 1 person, or there may not be at all), the task is to find people who are as similar as possible to the required pictures. That is, for example, 5-10 pictures of one person are given, and the tool finds the most similar people from the database.
Are there open source options available? Or advise - how to implement it better ....
Grateful for any kicks in the right direction!
It is necessary to search for exactly the identical content of the picture, and not the same pictures (that is, not just a comparison, but an analysis of the content). At the same time, pictures can be converted to the BW version and to the format, say, BMP .. There are no problems with this

Answer 1

Google facenet. There are ready implementations.

Answer 2

The task is certainly challenging and interesting! I only had to read the text from the pictures no more))

but on PYTHON - https://github.com/ageitgey/face_recognition , there is even a real-time search for specific faces.

Answer 3

Or advise - how best to implement it ....
Pattern recognition is a "classic" task for machine learning, neural networks and other related technologies, in theory, you need to google in this direction, but it seems unlikely to implement such an algorithm programmatically without the help of an experienced team ( from the word completely).

Answer 5

Picasa 3. Who would have known that the photo viewer can search for faces in images.
