Abstract:

 Automatic recognition of facial expression is an ac tive research topic in computer vision due to its importance in 
both human$computer and social interaction. One of the critical issues for a successful facial expression recognition system is 
to design a robust facial feature descriptor. Among the different existing methods, the Local Binary Pattern (LBP) has been 
proved to be a simple and effective one for facial expression representation. However, the LBP method thresholds P neighbors 
exactly at the value of the center pixel in a local neighborhood and encodes only the signs of the dif ferences between the gray 
values. Thus, it loses some important texture infor mation. In this paper, we present a robust facial f eature descriptor 
constructed with the Compound Local Binary Pattern (CLBP) for person$independent facial expression recognition, which 
overcomes the limitations of LBP. The proposed CLBP operator combines extra P bits with the original LBP code in order to 
construct a robust feature descriptor that exploits both the sign and the magnitude information of the differences between the 
center and the neighbor gray values. The recognitio n performance of the proposed method is evaluated u sing the Cohn$
Kanade (CK) and the Japanese Female Facial Expressi on (JAFFE) database with a Support Vector Machine (SVM) classifier. 
Experimental results with prototypic expressions sh ow the superiority of the CLBP feature descriptor a gainst some well$
known appearance$based feature representation metho ds.
