Detailed Description

Region-aware and matrix transformation functions leveraging existing ecosystem.

• Uses EnergyAnalyzer for region detection instead of manual implementation
• Leverages StatisticalAnalyzer for outlier detection instead of manual stats
• Uses ExtractionHelper functions for data extraction
• Uses normalization from MathematicalTransform where appropriate
