2D Generalized S-Transform Program with Test Suite

This package provides 2D generalized S-transform implementation and test programs for image time-frequency analysis. Developed for MATLAB R2011b on 32-bit Windows 7, the current implementation can process images up to 84x84 pixels with 2GB RAM. The code implements a novel algorithm for two-dimensional time-frequency decomposition using customized Gaussian window functions with frequency-dependent resolution.
