This system allows you to create sets of user profiles and then to search them using the face recognition mechanisms. Each of the profiles can have multiple photos for better recognition.
I have just started building it so there is still a lot of work to do. The first feature to be developed is API service for the project. It will be a RESTful service which will allow you to create your own collections of users and to search through them.
There are some available solutions (both open source and strictly commercial) on the market right now. But none of them are easy to be embedded into an existing application, while my service will allow it.
