摘要
In this paper, we introduce the concept of Self-Quotient Image (SQI) for robust face recognition under varying lighting conditions. It is based on the Quotient Image method [4][5] to achieve lighting invariant. However, the SQI has three advantages: (1) It needs only one face image for extraction of intrinsic lighting invariant property of a face while removing extrinsic factor corresponding to the lighting. (2)No alignment is needed. (3) It works in shadow regions. The theoretical analysis on conditions where the algorithm is applicable and a non-iterative filtering algorithm for computing SQI are presented. Experiment results demonstrate the effectiveness of our method for robust face recognition under varying lighting conditions.
