What are the services for image recognition?

Question

Algorithms

There is a price aggregator of clothes, 500 thousand goods with the addition / removal of about 10 thousand per day. All products must be categorized according to a number of criteria: gender, size, brand or color derickrethans.nl/finding-out-colours.html everything is clear with this. We take an attribute from the database and display it, but take, for example, the category “women's shoes”, there are attributes not listed in the database “shoes with heels”, “wedge shoes”, “shoes with a strap”.
Maybe there are solutions in the form of libraries, api services that allow you to mark up a product and assign it a category by image?

Answer 2

I re-read it three times and did not understand the campaign. Do you want to determine from the photo which category the product belongs to? This is hardly a viable option, besides resource-intensive. It is more correct to motivate sellers to fill out catalogs better.

Answer 3

With sellers, the option disappears, they are on the side of the store, there is no influence and control over them.
Yes, that's right, "from the photo".
It’s clear that it’s resource-intensive, so I’m looking, ideally, for a third-party solution

Answer 4

Try to tinker with the OpenCV library
