WebAug 13, 2015 · Well i was just saying because face detection uses around 24x24 pxiels for training and the face recognizer in OpenCV using the AT&T dataset uses sizes of 92x112 pixels. Seeing that you can get up to 92.7% correct recognition on AT&T I am pretty convinced that using for example 100x100 pixels is more than enough information.
