Adaptive Curvelet Thresholding for Filtering of Additive Stationary White/Colored Gaussian Noise

This package contains the denoising filter for additive stationary white/colored(a.k.a. correlated) Gaussian noise based on the adaptive curvelet thresholding (ACT) method presented in:

The ACT package includes:

ACT_filter.m the denoising filter based on ACT
demo_denoising.m a demo code for denoising of additive stationary Gaussian noise
./DCuT/fdct_wrapping.m forward discrete curvelet transform
./DCuT/ifdct_wrapping.m inverse/backward discrete curvelet transform
./Test_Images some images for testing the denoising performance

For a detailed information on each function, please check its corresponding syntax, e.g.,
