AI Technical Summary

Problems solved by technology

Since the size of the best matching block is 16x16 pixels, including 256 pixels, the volume is very large, which consumes hardware logic resources
Due to the above reasons, the interpolation of 1 / 4 sub-pixel reduces the processing capacity of the chip and increases the processing time

Abstract

The invention relates to a motion estimation method and apparatus of image frame data. The method comprises the following steps: obtaining the image frame data; determining an optimal pixel point in the image frame data; establishing a coordinate system of a block corresponding to the optimal pixel point, and obtaining coordinate information of a 1 / 4 sub-pixel point; determining the coordinate information of a corresponding specific pixel point according to the coordinate information of the 1 / 4 sub-pixel point; determining type information of the specific pixel point according to the coordinate information of the specific pixel point; obtaining a color value of the 1 / 4 sub-pixel point according to the type information of the specific pixel point and the coordinate information of the specific pixel point; and determining an optimal matching block of the image frame data according to the color value of the 1 / 4 sub-pixel point. By adoption of the method, the hardware resources can be reduced, the processing time can be shortened, the complexity of extracting the 1 / 4 sub-pixel point can be greatly reduced, and the real-time encoding and decoding of a high-definition video can be achieved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for motion estimation of image frame data. Background technique [0002] AVC (Advanced Video Coding) is jointly launched by the Joint Video Team (JVT, Joint Video Team) composed of the Video Coding Expert Group of the International Telecommunication Union and the motion picture experts of the International Organization for Standardization. It is a video codec standard dedicated to improving the compression ratio. . [0003] AVC-based video encoder mainly consists of intra-frame prediction, inter-frame prediction and other modules. Inter-frame prediction mainly utilizes the temporal correlation of video and is a block-based motion compensation technology. Its main principle is to find a best matching block in the coded image of the previous frame for each pixel block of the current image as a reference value, an...
