Image Inpainting Texture Strength Map Artifact Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image inpainting techniques fail to maintain textural continuity in restored areas due to the lack of consideration for unique, non-repetitive structures and texture information during the reconstruction process, resulting in artifacts.
Innovation Solution
A method and system that generate a texture strength map based on texture characteristics such as edge characteristics, contrast levels, and spatial frequencies to ensure textural continuity by analyzing and utilizing texture information during the inpainting process, using a texture descriptor generator and inpainting component to apply the inpainting operation based on the texture strength map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inpainting techniques copy pixels from similar patches without considering texture information, then the inpainting process is simple and fast, but textural continuity is not maintained and artifacts appear in restored areas
Solution Approach 1:
The patent applies preliminary action by generating a texture strength map before performing the inpainting operation. This map pre-characterizes the texture properties of the image, allowing the inpainting process to reference pre-computed texture information rather than analyzing textures during the actual restoration, thus maintaining textural continuity while managing complexity
Solution Approach 2:
The texture strength map serves as an intermediary between the original image and the inpainting process. It mediates the transfer of texture information by providing a separate data structure that encodes texture characteristics, which the inpainting algorithm then uses to guide pixel copying and blending operations
2Manufacturing precision
If texture analysis is performed during inpainting to maintain textural consistency, then textural continuity is improved, but computational complexity and processing time increase
Solution Approach 1:
The texture strength map is computed in advance before the inpainting operation begins. This preliminary computation separates the complex texture analysis from the time-critical inpainting process, allowing detailed texture characterization without extending the actual restoration time
Solution Approach 2:
The patent segments the inpainting process into distinct phases: texture analysis (generating the texture strength map) and restoration (using the map to guide inpainting). This segmentation allows each phase to be optimized independently, with the analysis phase being computationally intensive but time-independent, and the restoration phase being faster and reference-driven
