Fractional-Order Anisotropic Diffusion Image Denoising

Implementation of fractional-order anisotropic diffusion image denoising method from the paper "Fractional-Order Anisotropic Diffusion for Image Denoising" by Jian Bai and Xiang Chu, published in IEEE T. Image Process., 2007, 16(10): 2492-3502, featuring MATLAB-based implementation with diffusion coefficient optimization and edge preservation capabilities

3D Shape Reconstruction MATLAB Code with Shape-from-Defocus and Diffusion Techniques

This MATLAB implementation performs 3D shape reconstruction using shape-from-defocus methodology combined with diffusion processing. The algorithm enables complete 3D reconstruction from just two differently-focused images, significantly simplifying data acquisition while maintaining reconstruction accuracy through sophisticated depth-from-defocus calculations and diffusion-based noise reduction.
