Hello,

I'm using Opencv for face detection from video stream but my problem is how to assign an id for each detected face? for example if in the current frame i have detected 3 faces so i have 3 unique id for each faces, now in the next frame if i have 4 detected faces then i need an other id to assign it to the new face!!!

how i can assign a unique id for each faces?

also how i can preserve the same id for each face and assign a new id for the new detected face?

Thank you

Lafi

You will need a combination of a prediction algorithm and an assignment algorithm. A kalman filter+Hungarian algorithm for example.

Here's a C++ implementation to give you an idea so you can port it to python.
