Solution Overview

Problem

Existing region-based video filters incur overhead bits for coding segmentations, degrading overall performance due to independent partitioning and segmentation for multiple filters, which are not correlated with video content.

Innovation Solution

Implement collaborative partition coding where region partition information is shared among multiple filters, optimizing segmentation based on rate-distortion cost and video content, reducing redundant bit usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If independent partitioning is performed for multiple region-based filters, then each filter can adapt to local content characteristics, but the overhead bits for coding segmentations increase and overall performance degrades

Engineering Contradiction:

Improvefilter adaptation to local contentVSAvoidoverhead bits for segmentation coding

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent merges the segmentation coding process for multiple filters into a single collaborative partition coding process. Instead of independently coding segmentations for each filter, the system performs one segmentation coding operation that serves all filters, thereby eliminating redundant overhead bits while preserving the ability of each filter to adapt to local content characteristics through shared partition information.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple region-based filters perform independent segmentation, then each filter optimizes for its specific function, but the bits paid for coding segmentations for all filters become demanding and reduce overall gain

Engineering Contradiction:

Improvefilter-specific optimizationVSAvoidcoding efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements a universal segmentation coding mechanism that serves multiple filters simultaneously. The collaborative partition coding process creates a single segmentation structure that can be utilized by all region-based filters, making the coding system more efficient by eliminating redundant segmentation coding operations while still allowing each filter to perform its specific optimization functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If region partition information is not shared between filters, then each filter has full freedom in partitioning, but redundant partition information is transmitted and overhead increases

Engineering Contradiction:

Improvefilter partitioning freedomVSAvoidpartition information redundancy

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the partition information storage across multiple filters into a single shared structure. Instead of each filter maintaining its own partition information independently, the system uses a unified partition information structure that is shared among all filters, thereby eliminating redundancy while preserving the adaptability needed for effective filtering.

Inventive Principle:

Principle #5Merging (Combining)
