Explore MATLAB source code curated for "NSCT变换" with clean implementations, documentation, and examples.
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.
Application Background: This MATLAB experiment focuses on multi-focus image fusion, utilizing source images such as "pepsi" and "clock". The program has been modified with improvements to high/low-frequency algorithms, ensuring stability for graduation thesis use. Key Technologies: Implements image fusion through point-wise NSCT transformation using the NSCT toolbox, employing maximum pixel method for low-frequency components and maximum variance method for high-frequency components. Enhanced algorithm incorporates pixel correlation-based fusion methodology.
