MATLAB Bilateral Filter Implementation

The bilateral filter is an edge-preserving noise reduction filter that achieves its denoising effect through two component functions. One function determines filter coefficients based on geometric spatial distance, while the other uses pixel intensity differences to calculate coefficients. The implementation includes main.m as the program entry point that handles parameter initialization and workflow coordination, and bfilter2.m as the core filtering function that executes the bilateral filtering algorithm with configurable spatial and range sigma parameters.
