3D Image Matching Using Gaussian Convolution for Keypoint Detection

This MATLAB program implements 3D image matching by utilizing Gaussian convolution for keypoint detection, followed by feature vector extraction at keypoint locations and 3D vector matching to achieve 3D image registration.

Smooth Noise Reduction for 3D Images using Perona-Malik Anisotropic Diffusion Model

Implementation of Perona-Malik anisotropic diffusion model for smoothing and denoising 3D images, effectively suppressing Gaussian noise while preserving edge features through gradient-controlled diffusion processes.
