Facial Expression Recognition Based on Multi-Feature Fusion and HOSVD

This paper proposed a facial expression recognition algorithm based on geometric and texture fusion features and HOSVD (High-Order Singular Value Decomposition) to the problem of low recognition rate for human independent facial expression. The algorithm transforms the facial expression recognition problem into the tensor domain, and extracts human independent expression features using HOSVD. 

Then the interference caused by individual face differences on expression recognition is effectively excluded. The algorithm was tested on the Japanese Female Facial Expression database, and the results showed that the method achieved better recognition rate in human-independent experiments.
