Abstract

The invention relates to a pixel position determination method and device, electronic equipment and a storage medium, and the method comprises the steps: sequentially calculating the position evaluation parameters of all predicted pixel positions according to the calculation sequence of all predicted pixel positions of M * N sub-blocks of a current coding block in a motion estimation process of display stream compression coding, stopping the calculation of the remaining predicted pixel positions until the position evaluation parameters meet the preset requirements; and selecting one of the calculated predicted pixel positions as a target pixel position for motion estimation of the M * N sub-blocks. By adopting the method, the complexity of motion estimation of the pixel position can be reduced.

Description

technical field

[0001] The present application relates to the technical field of display stream compression, and in particular to a method, device, electronic device and storage medium for determining a pixel position. Background technique

[0002] In order to achieve low-cost, visually lossless and high-efficiency video compression in the display link, many advanced compression coding tools are used in VDC-M, such as Block Prediction (BP), which divides the coding block into M*N sub-blocks , for example, an 8x2 coding block will be divided into 4 2x2 and 8 2x1 sub-blocks, and each 2x2 and 2x1 sub-block needs to move 64 positions at the adjacent coded pixel positions of the current coding block Estimate, and choose an optimal position as the optimal prediction position of the sub-block, so as to remove the spatial information redundancy.

[0003] However, motion estimation is required for all pixel positions, resulting in high complexity in determining motion estimation for...
