1Measurement precision
If conventional image processing techniques are applied uniformly across the entire image, then the processing is simple and fast, but the results are unsatisfactory due to misunderstanding of local image context
Solution Approach 1:
The image is divided into multiple local regions or blocks, and each region is processed independently with its own classification and processing parameters. This segmentation allows the system to capture local image context while maintaining manageable computational complexity through parallel processing of discrete regions.
Solution Approach 2:
Different processing techniques and parameters are applied to different local regions based on their specific characteristics (smooth, weak feature, or strong feature areas). This local quality approach ensures that each region receives the most appropriate processing for its specific context, improving overall image processing accuracy.
2Measurement precision
If multiple processing techniques are applied to different regions, then the image processing accuracy is improved, but the processing time and computational complexity increase
Solution Approach 1:
The system performs preliminary classification of each local region into smooth, weak feature, or strong feature areas before applying specific processing techniques. This preliminary action allows the system to quickly identify region types and select appropriate processing paths, reducing overall processing time while maintaining accuracy.
Solution Approach 2:
The system changes processing parameters based on the classified region type, applying different techniques for smooth areas versus feature-containing areas. This parameter adaptation allows efficient processing by matching computational effort to the actual complexity of each region.
3Reliability
If detailed local analysis is performed on each region, then the processing accuracy is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The image processing system is segmented into distinct functional modules: classification module, processing module, and fuzzy logic module. Each module performs a specific function, making the overall complex system manageable through modular design while maintaining high processing reliability.
Solution Approach 2:
The system uses fuzzy logic to automatically determine processing parameters and techniques based on local region characteristics without requiring manual intervention or complex external control systems. This self-service capability improves reliability while avoiding the complexity of manual system configuration.

AI summary
In one respect, provided are systems, methods and techniques in which local regions within an image are processed to provide fuzzy classification scores, which are calculated by determining changes in pixel values along a number of different directions. The resulting fuzzy classification scores are then used to detect or identify edge-containing or texture-containing regions, or to otherwise process the image regions differentially according to their fuzzy classification score. In another respect, provided are systems, methods and techniques for differential processing of different areas in an image. The differential processing in this case is based on calculated measures of local activity, which indicate features in corresponding local regions, and also based on calculated measures of local pixel-value variations, which indicate an amount of variation in pixel values across the corresponding local regions.
