Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional video coding technologies (MPEG-2, MPEG-4, AVC, HEVC, VVC) are used, then video compression is achieved, but coding efficiency is insufficient

Engineering Contradiction:

Improvecoding efficiencyVSAvoidcompression performance

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent applies filter-based prediction methods that transform the prediction process by applying filters (such as gradient filters, bilateral filters, or guided filters) to reference blocks before generating predictions. This parameter transformation improves prediction accuracy and coding efficiency compared to conventional direct prediction methods

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces conventional mechanical prediction methods with filter-based prediction mechanisms. Instead of using simple copying or linear interpolation, the system uses filtering operations (convolution, bilateral filtering, guided filtering) to generate more accurate predictions, thereby improving compression performance

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If filter-based prediction methods are implemented, then coding efficiency is improved, but computational complexity increases

Engineering Contradiction:

Improvecoding effectivenessVSAvoidprocessing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the video processing into distinct stages: reference block selection, filter application, and prediction generation. By segmenting the process and applying filters only to specific reference blocks based on mode selection, the computational complexity is managed while maintaining improved coding effectiveness

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies filter-based prediction selectively rather than to all blocks. Mode flags determine whether filter-based prediction is applied, allowing the system to use enhanced methods only where beneficial, thus balancing complexity and effectiveness

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. In the method, for a conversion between a current video region of a video and a bitstream of the video, a filter-based non-intra or intra prediction of the current video region is determined on a basis of one of: a transform unit (TU), a coding unit (CU), a prediction unit (PU), or a subblock. The conversion is performed based on the filter-based non-intra or intra prediction.
