Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inter prediction methods in video encoding affect the accuracy and efficiency of inter prediction, necessitating an improved approach for video data processing.
Innovation Solution
A system and method for inter prediction based on a Merge mode, which involves determining whether a current block in an image frame satisfies a division condition, and if so, dividing it into two sub-blocks using a rectangular division mode. This division mode can be converted from an inclined division, and motion compensation is performed on the sub-blocks to determine the prediction result of the current block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current inter prediction methods are used, then video encoding can be performed, but the accuracy and efficiency of inter prediction deteriorates
Solution Approach 1:
The current block is divided into two sub-blocks through rectangular or inclined division, allowing separate motion compensation processing for each sub-block. This segmentation enables more accurate prediction by capturing different motion characteristics in different regions, while the systematic division approach maintains processing efficiency
Solution Approach 2:
Different motion compensation operations are applied to different sub-blocks based on their local characteristics. Each sub-block can have its own motion vector and prediction parameters, allowing the prediction accuracy to be optimized locally without compromising overall encoding efficiency
2Measurement precision
If block division is performed to improve prediction accuracy, then inter prediction accuracy improves, but computational complexity increases
Solution Approach 1:
The block is divided into a limited number of sub-blocks (typically two) using systematic rectangular or inclined division patterns. This controlled segmentation improves prediction accuracy by capturing local motion variations while keeping the computational overhead manageable through the regular division structure
Solution Approach 2:
Motion compensation is applied selectively to sub-blocks that benefit from it, rather than uniformly to the entire block. The division and processing is performed only when it provides meaningful improvement, avoiding unnecessary computational complexity in cases where simple prediction suffices
