Geometric normalization is to determine the main rectangular feature region according to the sum of feature points and geometric model of facial expression image, and then cut the original size of 256×256 image into 150×100 image, so that the size of the face in the image is consistent.	cache/fcis-3178.pdf	txt/fcis-3178.txt
