Robustness Analysis on Facial Image Description in DCT Domain

Main information
In this letter, we report a DCT domain analysis of facial images to reveal that, when certain number of DCT coefficients are removed, the corresponding facial image description by the remaining DCT coefficients becomes robust to lighting changes and scale variations. Such nice properties would be very useful for applications of face recognition, video object tracking, object segmentation and visual content processing.
