We are looking for an efficient camera to use for our machine learning application (body tracking and emotion detection). Through my readings, it seems using an IR filter for our camera is quite important. However, most machine learning specialized cameras are grayscale cameras and don’t have IR Filter. We need to add IR LEDs for our camera in order to enable the night vision features.
It seems confusing for me, Am I missing anything or it doesn’t make sense to have IR cut filter and IR LEDs when using a grayscale image sensor? Would you add your thoughts and recommend any useful, and simple articles that explains the same subject?
