Texture feature extraction and optimization of facial expression based on weakly supervised clustering

Texture feature extraction and optimization of facial expression based on weakly supervised clustering

In order to improve the recognition rate of weak annotation data in facial expression recognition task, this paper proposes a multi-scale and multi-region vector triangle texture feature extraction scheme based on weakly supervised clustering algorithm. According to the information gain rate of extr...
