MATLAB code for Local Gray Code Pattern (LGCP) descriptor

Description

Local Gray Code Pattern (LGCP) descriptor is a novel method for facial feature extraction, which is insensitive to noise, and nonmonotonous illumination changes.

The method encodes spatial structure along with local contrast information for facial expression recognition. Extensive experiments prove that the proposed method is effective and efficient for expression recognition.
