MATLAB Code for Shadow Detection Using Illumination-Invariant Transformation

Background: This shadow detection method was proposed by Mr. J.W. Hofstee and Mr. E.J. Hanten in their paper "Shadow Segmentation Based on Image Transformation for Illumination Changes" presented at the International Conference on Agricultural Engineering in Zurich (July 6-10). Key Technology: Implements shadow detection through illumination-invariant image transformation. The algorithm successfully detects shadows in certain images but shows varying performance across different image types, indicating potential areas for optimization in practical implementations.
