Explore MATLAB source code curated for "PSNR" with clean implementations, documentation, and examples.
Several MATLAB-based image processing utilities focusing on PSNR (Peak Signal-to-Noise Ratio) and MSE (Mean Squared Error) calculations, designed to assist researchers in image quality assessment and compression analysis.
A clear and practical implementation of the BM3D algorithm for image denoising in MATLAB, including PSNR calculation for performance evaluation. This code demonstrates block-matching, 3D transforms, and collaborative filtering techniques to effectively reduce noise while preserving image details.
This directory contains programs for wavelet-based image denoising using neighborhood thresholding techniques. The main script wave_neighbor.m implements denoising for both 3×3 and 5×5 neighborhood configurations. The auxiliary function wov_win.m handles sliding window operations for 3×3 and 5×5 neighborhoods, while cacupsnr.m calculates performance metrics including Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR).
