Four MATLAB Demos for PUMA Algorithm Implementation

%%% Demos for PUMA Algorithms %%% We present four comprehensive MATLAB demonstrations for the PUMA (Phase Unwrapping Max-flow/min-cut Algorithm). demo1, demo2, demo3, and demo4 showcase PUMA's performance with varying parameters across four distinct test images. Each demo includes complete implementation with configurable parameters and visualization of phase unwrapping results. Users simply need to execute each demo script, ensuring proper MATLAB path configuration.
