What is Facial Expression Recognition Methods about?

This document compares two approaches to facial expression recognition using a multi-layer perceptron: 1) using the geometric positions of fiducial points on the face as features and 2) using Gabor wavelet coefficients extracted from fiducial points. It finds that Gabor wavelet coefficients are more powerful features for recognition compared to geometric positions alone. It also studies the optimal number of hidden units (5-7) needed in the first layer of the perceptron to achieve good recognition rates whi
