Non-Subsampled Contourlet Transform (NSCT)

Non-Subsampled Contourlet Transform (NSCT) – primarily used for image denoising with exceptional effectiveness, implementing multi-directional and multi-scale decomposition without downsampling to preserve image details.

NSCT Toolbox (MATLAB) - Nonsubsampled Contourlet Transform Implementation

MATLAB implementation of nonsubsampled contourlet transform (NSCT) - Note: This toolbox was originally designed for 32-bit MATLAB and may encounter compatibility issues when running on 64-bit MATLAB systems. After downloading, users need to compile (mex) three C source files (.c) as specified in the compressed package documentation. The toolbox provides multi-scale and multi-directional image decomposition capabilities using directional filter banks and pyramid decomposition structures.
