Video inter-frame motion estimation method, device, device and readable storage medium

Abstract

The embodiment of the present invention discloses a video inter-frame motion estimation method, device, equipment and computer-readable storage medium. Wherein, the method includes first determining the reference macroblocks of m reference frame images of the current coded macroblock of the current frame image, and then determining the termination search condition according to the SAD values ​​of the m reference macroblocks; the reference frame image set image of the current frame image The total number is n, and m<n; in the process of determining the reference macroblock for the remaining n-m reference frame images in the reference frame image set for the first encoded macroblock, if the SAD value of the currently retrieved macroblock of the current reference frame image satisfies When the search condition is terminated, the retrieval of the current reference frame image is stopped. The application effectively improves the motion estimation speed between video frames, which is beneficial to the stable and efficient operation of the system.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video coding, and in particular, relate to a video inter-frame motion estimation method, device, equipment, and computer-readable storage medium. Background technique [0002] With the rapid development of computer network technology, the demand for video data and video quality requirements are also getting higher and higher. [0003] In video coding and decoding, each frame of image is usually divided into multiple non-overlapping blocks, and assuming that all pixels in the block have the same displacement, the encoding of the entire frame of image is decomposed into the number of each macroblock in the frame. Coding, that is, data processing with macroblocks as the smallest unit. It is necessary to determine a reference macroblock from each reference image frame for each macroblock in each image frame, and use the relative displacement between the reference macroblock and the curr...

Problems solved by technology

[0005] Since each reference frame needs to be searched and calculated, the amount of calculation is still huge, and there are many redundant calculations. Not only is the motion estimation between video frames inefficient, but also the central processing unit’s computing resources are wasted, which is not conducive to system stability. run efficiently
