Translation-Invariant Wavelet Denoising
Translation-invariant wavelet denoising delivers excellent performance that I particularly appreciate, with robust signal processing capabilities maintainable through circular shifting implementations
Non-Subsampled Contourlet Transform: An Advanced Development Based on Contourlet Transform
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.
