WebSupporting: 2, Mentioning: 27 - We analyze the detection and classification of singularities of functions f = χS, where S ⊂ R d and d = 2, 3. It will be shown how the set ∂S can be extracted by a continuous shearlet transform associated with compactly supported shearlets. Furthermore, if ∂S is a d−1 dimensional piecewise smooth manifold with d = 2 … WebConsidering the geometric structure of the corners, a new anisotropic diffusion method taking into consideration the image local multi-directional information was designed at first to achieve significant denoising effect and preserve the edge information and detailed information of the image.
