Abstract
A time-domain filtering method is provided, including: determining a to-be-filtered image frame in a group of pictures; extracting a relative motion feature of the to-be-filtered image frame, where 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.
