WebIn this paper, we focus on the generalization of anisotropic dif- fusion, a PDE-based,edge-preserving,image-smoothingtechnique, to surface processing. The proposed method offers two advantages over previous work on feature-preservingsmoothing of surfaces. Webment. The first method is based on the curvature-driven min/max flow and originates from the level set methods. The second method is an anisotropy diffusion flow. The curvature-driven method seems to enhance better the significant edges in the image, whereas the anisotropic diffusion seems to work better with smoothing intra-regional …

Webthe anisotropic diffusion is sensitive to noise as the whole model is gradient-driven[6], which often suffers the staircase effect and the loss of edge details when the image contains a high level of noise[7]. To overcome this shortcoming, we propose a difference curvature driven anisotropic diffusion to smooth noisy images in this paper. WebA geometric model for a biologically-inspired visual front-end is proposed, based on an isotropic, scale-invariant two-form field. The model incorporates a foveal property typical of biological visual systems, with an approximately linear decrease of resolution as a function of eccentricity, and by a physical size constant that measures the radius of the geometric …
