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

Abstract

The embodiment of the invention discloses a video inter-frame motion estimation method, device and equipment and a computer readable storage medium. The method comprises the following steps: firstly, determining reference macro blocks of m reference frame images of a current coding macro block of a current frame image, and then determining a search termination condition according to SAD values of the m reference macro blocks, wherein the total number of images in the reference frame image set of the current frame image is n, and m is less than n; in the process of determining the reference macroblock for remaining n-m reference frame images in a first coded macroblock set, if the SAD value of the current retrieval macro block of the current reference frame image meets a search termination condition, stopping retrieving the current reference frame image. According to the method, the video inter-frame motion estimation speed is effectively increased, and stable and efficient operation of the system is facilitated.

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...
