1. An electronic device, comprising: one or more processors, a memory, a communication interface, and a communication bus, wherein the one or more processors, the memory, and the communication interface communicate with each other through the communication bus; and
wherein the memory is configured to store at least one executable instruction, and the executable instruction enables the one or more processors to cause the electronic device to perform operations comprising:
determining a to-be-filtered image frame in a group of pictures;
extracting a relative motion feature of the to-be-filtered image frame, wherein the relative motion feature represents relative motion complexity between image contents of the to-be-filtered image frame and image contents of the remaining image frames in the group of pictures; and
determining a target filtering magnitude corresponding to the relative motion feature, and performing time-domain filtering on the to-be-filtered image frame by using the target filtering magnitude.
