In many existing multi-view gait recognition methods based on images or video sequences, gait sequences are usually used to superimpose and synthesize images and construct energy-like template. However, information may be lost during the process of compositing image and capture EMG signals. Errors and the recognition accuracy may be introduced and affected respectively by some factors such as period detection. To better solve the problems, a multi-view gait recognition method using deep convolutional neural network and channel attention mechanism is proposed. Firstly, the sliding time window method is used to capture EMG signals. Then, the back-propagation learning algorithm is used to train each layer of convolution, which improves the learning ability of the convolutional neural network. Finally, the channel attention mechanism is integrated into the neural network, which will improve the ability of expressing gait features. And a classifier is used to classify gait. As can be shown from experimental results on two public datasets, OULP and CASIA-B, the recognition rate of the proposed method can be achieved at 88.44% and 97.25% respectively. As can be shown from the comparative experimental results, the proposed method has better recognition effect than several other newer convolutional neural network methods. Therefore, the combination of convolutional neural network and channel attention mechanism is of great value for gait recognition.
