An extension of Chain Code-Based Local Descriptor (CCBLD) is proposed. CCBLD is applied to face recognition task. Bag-of-Visual-Words paradigm is realized through the dictionary of chain-codes. Test results show that CCBLD is comparable or outperforms other local descriptors. The approach is tested using CAS-PEAL, ColorFERET, FG-NET, and other datasets.
