%%% Demonstrations for PUMA Algorithm %%% We provide four MATLAB demonstrations for the PUMA phase unwrapping algorithm. demo1, demo2, demo3, and demo4 illustrate PUMA operating with different parameter settings and processing four distinct sample images. The implementation utilizes graph-cut optimization techniques for robust phase unwrapping. Each demo contains: parameter initialization, image loading, PUMA algorithm execution with max-flow/min-cut optimization, and result visualization. Simply run each demo script sequentially. Ensure all files are located within MATLAB's accessible path. Note: This code is intended for research purposes only. For detailed algorithm explanation, refer to "Phase Unwrapping via Graph Cuts, IEEE Transactions on Image Processing, 2007". The demos demonstrate key functions including energy minimization, regularization parameter effects, and quality metrics evaluation.
