Title:
VIDEO ENHANCEMENT METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/218414
Kind Code:
A1
Abstract:
A video enhancement method and apparatus, and an electronic device and a storage medium, which relate to the technical field of image processing. The method comprises: extracting features from M frames of images, so as to obtain at least one first-scale image feature (S310); for each first-scale image feature, performing N-level down-sampling processing on the first-scale image feature, so as to obtain a second-scale image feature (S320); performing N-level up-sampling processing on the second-scale image feature, so as to obtain a third-scale image feature (S330), wherein the input of ith-level up-sampling processing is an image feature obtained after performing superimposition processing on the output of (N+1-i)th-level down-sampling processing and the output of (i-1)th-level up-sampling processing, and the multiple of jth-level up-sampling is the same as the multiple of (N+1-j)th-level down-sampling; and performing superimposition processing on the third-scale image feature and the first-scale image feature, so as to obtain an enhanced image corresponding to the first-scale image feature (S340). The efficiency and effect of video enhancement can be improved.
