Abstract: A video encoding method includes obtaining a current image frame, performing video image enhancement on a target region in the current image frame, to generate an image-enhanced image frame, the target region including a region in which hopping occurs in a pixel value of a pixel in the current image frame, and encoding the image-enhanced image frame.

Abstract: A video processing collaboration method includes transmitting a video processing capability request and a video analysis capability request to a terminal device, receiving video processing capability information and video analysis capability information from the terminal device based on the video processing capability request and the video analysis capability request, determining a video processing collaboration configuration based on the video processing capability information and a video analysis collaboration configuration based on the video analysis capability information, allocating an image processing task to the terminal device, to the cloud server, or to both the terminal device and the cloud server, based on the video processing collaboration configuration, and allocating an image analysis task to the terminal device, to the cloud server, or to both the terminal device and the cloud server, based on the video analysis collaboration configuration.

Abstract: This application relates to a battery module, including a substrate, battery units, end plates, side plates and fastening pieces; the end plates are respectively located on two sides of the battery units in their stacking direction, adjacent to outermost ones of the battery units and extend along a length direction of the battery unit; an end of the end plate in the length direction is curled into a pipe and forms a curling pipe section, an axial direction of the curling pipe section is the same with a height direction of the battery unit; the fastening piece is inserted in the curling pipe section, extends in the curling pipe section toward the substrate and protrudes out of the curling pipe section, and are fixed on the substrate; by configuring curling pipe sections, fastening strength is improved, so as to realize reliable fixation of the battery module on the substrate.
