Super-resolution processing method for videos

The invention discloses a super-resolution processing method for videos. The super-resolution processing method comprises the following steps: carrying out the following processing operations on all frame images in received videos to be processed, namely (1) dividing the current frame image into a plurality of image blocks; (2) respectively carrying out the following processing on all image blocks in the current frame image, so as to obtain super-resolution image blocks of all the image blocks, namely 1) detecting similar blocks of the current block; 2) carrying out up-sampling processing on a plurality of similar blocks of the current image block, so as to obtain up-sampling image blocks of all the similar blocks; and 3) fusing the up-sampling image blocks of all the similar blocks into a super-resolution image block; and (3) integrating the super-resolution image blocks of all the image blocks into an image according to the positions of all the image blocks in the current frame image so as to obtain a super-resolution processing image of the current frame image. The super-resolution processing method disclosed by the invention has the advantages that by utilization of similar image blocks in a space domain and/or similar image blocks in a time domain, the processing effect can be improved.
