Illumination-robust face recognition with Block-based Local Contrast Patterns

Yichuan Wang, Zhen Xu, Weifeng Li, Qingmin Liao

ICASSP 2017accepted

This paper proposes a novel facial image representation Block-based Local Contrast Patterns (BLCP) for illumination-robust face recognition. This method is based on an effective texture descriptor local contrast patterns (LCP). We use the directed and undirected difference masks to calculate three t…

Face recognition with local contourlet combined patterns

Yichuan Wang, Shilian Yu, Weifeng Li, Longbiao Wang, Qingmin Liao

ICASSP 2016accepted

This paper proposes a novel face image descriptor called local contourlet combined patterns (LCCP), based on the Non-Subsampled Contourlet Transform (NSCT), for face recognition. NSCT is a multiresolution analysis tool and can capture image information at multiple scales, orientations, and frequency…
