The invention provides a method for removing video jitter. The method comprises the steps that according to position information of feature point pairs in each pair of compressed images, the positioninformation of the feature point pairs in each pair of original images is determined, one feature point pair is composed of two corresponding feature points on a front image and a rear image in each pair of images, and the original images are images before compression; according to the position information of the feature point pairs in each pair of original images, the position transformation information of the latter image relative to the former image in each pair of original images is determined; deformation information corresponding to the previous image in the mth pair of original images is acquired according to the position transformation information of the next image in the n pairs of original images relative to the previous image, n and m are positive integers, and m is not larger than n; and the previous image in the mth pair of original images is deformed according to the deformation information corresponding to the previous image in the mth pair of original images to obtain the jitter-removed previous image in the mth pair of original images. Through the above steps, video jitter is removed in real time.
Description
technical field [0001] The present application relates to the field of video processing, in particular to a method and device for removing video shake. The present application also relates to an electronic device and a computer-readable storage medium. Background technique [0002] A period of video is formed by many frames of images changing in rapid succession. When shooting a video, due to the relative motion between the video capture device and the scene, there will be a large displacement between the captured fast-changing images, so the video will appear jittery. [0003] The video de-jitter solution in the prior art is a non-real-time de-jitter solution, which cannot meet the real-time processing requirements of live video and short video. Contents of the invention [0004] The present application provides a method for removing video jitter, aiming at solving the technical problem that real-time de-jitter cannot be achieved in the prior art. [0005] The present ...
