Latest Patents

Diantong Liu holds a patent for an "Expression recognition method and system based on multi-scale features and spatial attention." This invention relates to the technical field of expression recognition. The method involves performing feature extraction on acquired facial image data using an HNFER neural network model to obtain an original input feature map. It further includes pooling and concatenation of extracted features based on a CoordAtt attention mechanism to create a feature map. The process continues with deep convolution processing to obtain an attention map, followed by element-by-element multiplication to derive a final feature map. Finally, feature transformation and normalization are performed to output an expression category probability. This innovative approach integrates scale perception and spatial attention technologies, allowing for more accurate recognition and classification of different emotional states, even in complex environmental conditions.
