Inter-Frame Prediction Correction for Video Block Boundaries

The patent applies local quality by differentiating the treatment of boundary pixel points from internal pixel points. Specifically, boundary pixel points are identified and subjected to a specialized correction process that considers motion differences between adjacent blocks, while internal pixel points use standard prediction. This localized approach improves prediction accuracy at block boundaries without unnecessarily complicating the processing of all pixels.

The patent changes the parameter of motion compensation by introducing motion difference consideration into the prediction process. Instead of using a single motion vector for the entire block, the method calculates motion differences between adjacent blocks and uses these differences to adjust the prediction values at boundary pixel points, thereby adapting the prediction parameters to local motion characteristics.

The patent segments the prediction process into distinct stages: obtaining motion information for adjacent blocks, calculating motion differences, identifying boundary pixel points, and applying correction only where needed. This segmentation allows the system to manage computational complexity by breaking down the complex task of boundary prediction into manageable steps that can be executed efficiently.

The patent applies partial action by restricting the complex motion difference correction process to only boundary pixel points rather than applying it to all pixels in the block. This partial application of the correction method maintains improved accuracy at critical boundary regions while avoiding the excessive computational cost of processing every pixel with the same level of detail.
