Claim 9:
10. An action recognition apparatus, comprising a memory and one or more processors, the memory storing computer-readable instructions, the computer-readable instructions, when executed by the one or more processors, causing the one or more processors to:
obtain image data of video data in a plurality of different temporal frames;
obtain original feature submaps of each of the temporal frames on a plurality of different convolutional channels by using a multi-channel convolutional layer;
calculate, by using each of the temporal frames as a target temporal frame, motion information weights of the target temporal frame on the convolutional channels according to original feature submaps of the target temporal frame on the convolutional channels and original feature submaps of a next temporal frame adjacent to the target temporal frame on the convolutional channels;
obtain motion information feature maps of the target temporal frame on the convolutional channels according to the motion information weights and the original feature submaps of the target temporal frame on the convolutional channels;
perform temporal convolution on the motion information feature maps to obtain temporal motion feature maps of the target temporal frame on the convolutional channels; and
recognize an action type of a moving object in image data of the target temporal frame according to the temporal motion feature maps.
