Local Relation Map: A Novel Illumination Invariant Face Recognition Approach
International Journal of Advanced Robotic Systems
In this paper, a novel illumination invariant face recognition approach is proposed. Different from most existing methods, an additive term as noise is considered in the face model under varying illuminations in addition to a multiplicative illumination term. High frequency coefficients of Discrete Cosine Transform (DCT) are discarded to eliminate the effect caused by noise. Based on the local characteristics of the human face, a simple but effective illumination invariant feature localdoi:10.5772/51667 fatcat:5z6z7ozjqfgaxnblgrwytsaklq
