In order to overcome the influence of the two factors of small amount of data in the open facial expression data set
and there are certain similarities in some categories of expressions on facial expression recognition rate
a facial expression classification algorithm based on key region feature fusion is proposed.This algorithm firstly extract the key regions of facial expressions in the image
then extracts and fuses the feature information of the key regions
and finally uses the fused features for classification.Through experimental verification the algorithm achieves good identification accuracy in JAFFE dataset and the CK+ dataset.
