Skeleton Action Recognition Based on Dense Residual Shift Graph Convolutional Network
In order to solve the problem of recognition results of similar behaviors not being ideal owing to insufficient extraction of spatio-temporal features, a large amount of network computing, and low computing efficiency in human skeleton behavior recognition, a skeleton behavior recognition algorithm based on dense residual shift bitmap convolution network is proposed. The pose estimation algorithm is used to extract human skeleton information, and the joint, skeleton, and motion information of the skeleton are calculated by coordinate vector, and input into the network respectively. The dense residual structure is introduced between the shift graph convolution modules to improve the network performance and efficiency of extracting spatio-temporal features. The proposed algorithm can be applied to daily behavior, such as walking, sitting, standing up, undressing, dressing, throwing, and falling. The recognition accuracy on the self-made dataset is 81.7%, and under the two evaluation criteria of NTU60 RGB+D dataset, the accuracy is 88.1% and 95.3%, respectively, thus validating that the algorithm has excellent recognition accuracy.
