Detailed Documentation
This program implements Weickert's structure tensor diffusion denoising model. The model analyzes local structural features of images through structure tensor computation and performs denoising based on this analysis. During the image denoising process, the model effectively removes noise while preserving edge information through anisotropic diffusion controlled by the tensor field. The core implementation involves calculating the structure tensor matrix for each pixel neighborhood, determining diffusion coefficients based on tensor eigenvalues, and applying PDE-based diffusion filtering. Additionally, this model can be adapted for other image processing tasks such as image enhancement and segmentation through parameter adjustment of the diffusion tensor. The algorithm typically employs finite difference methods for PDE discretization and uses eigenvalue decomposition to guide directional diffusion processes.
