执行面部识别时的opencv light问题

Question

I am currently working on Face recognition using opencv with LBPH algorithm. But I am getting issue that I have trained many faces at evening of different person and it was working at that time, but the next day I am not getting the same result.

What are the best possible ways to handle this issue?

I will really appreciate any help.

Answer 1

In order to increase your Face Recognition System accuracy you should train your network on images of the different individuals photographed in different ambients, at different time during the day, from different distances, in different poses and with different illumination setups.

Once you have acquired this dataset, retrain your network on it and you should see that the predicition confidence increases and false positive decrease accordingly.

Hope this helps.
