NSCT - Non-Subsampled Contourlet Transform MATLAB Toolbox

The Non-Subsampled Contourlet Transform (NSCT) is a multi-scale, multi-directional image transformation method that provides excellent image representation and processing capabilities. This transform achieves high image compression rates and superior feature extraction performance. NSCT finds extensive applications in signal processing, image processing, computer vision, and related fields. The MATLAB implementation includes key functions such as nsctdec() for decomposition and nsctrec() for reconstruction, employing a dual-filter bank structure with non-subsampled pyramid and directional filter banks. The toolbox contains complete demonstration scripts showing how to configure decomposition levels, directional filters, and handle various image formats. If you need to perform NSCT transformations, you can utilize this MATLAB toolbox which includes detailed commands, configuration parameters, and comprehensive usage documentation for both academic and industrial applications.
