Abstract:
A method for real-time video noise reduction in a coding process comprises: obtaining a current frame of an image and a flat region of the current frame; performing noise reduction processing on the flat region; determining whether the current frame is a P frame; if yes, reading a sub macro block of the current frame; if not, ending the process; determining whether the read current sub macro block is an inter-frame sub macro block; if yes, performing integer discrete cosine transform and noise reduction processing on the read current sub macro block, then determining whether the read current sub macro block is a last inter-frame sub macro block of the current frame; if yes, ending the process; and otherwise, reading a next sub macro block, and entering the step of determining whether the read current sub macro block is an inter-frame sub macro block.
