Image Denoising and Processing Toolkit

This source code package provides comprehensive image processing capabilities including image denoising, image inpainting, and PSNR calculation, primarily implemented using total variation methods and other advanced techniques.

Soft Threshold Wavelet Denoising with Haar Wavelet - Implementation and Analysis

Soft threshold wavelet denoising using Haar wavelet.rar - Set the file directory as working directory, open wavlet.fig, input noise intensity (0-0.1, non-zero) in the noise prompt box, click process button to display experimental results including original image, noisy image, denoised image comparison and current PSNR value. wavlet.m contains the main program implementation with Haar wavelet transformation and soft thresholding algorithm.
