Non-subsampled contourlet correlation denoising research implementation, including a complete non-subsampled contourlet transform toolbox with verified simulation results and MATLAB-based algorithm demonstration
The Nonsubsampled Contourlet Transform (NSCT) is an advanced multi-scale geometric analysis approach that effectively characterizes linear singularity features in signals through multi-directional filter banks, enabling comprehensive signal decomposition across scales and orientations.
The Non-Subsampled Contourlet Transform (NSCT), developed from the Contourlet transform foundation, achieves translation-invariant properties in image transformation. This multiscale and multidirectional decomposition technique can be implemented using filter bank structures without downsampling operations, preserving spatial consistency across decomposition levels.
The combination of PCNN and non-downsampling not only reduces computational time but also enhances system efficiency through optimized feature extraction and multi-resolution analysis.
