Edges and corners with shearlets

Webedge detection and analysis are presented. Unlike previously developed directional filter based techniques for edge detec-tion, shearlets provide a theoretical basis for characterizing how edges will behave in such representations. Experiments demonstrate that this novel approach is very competitive for the purpose of edge detection and analysis. WebEdges and Corners With Shearlets Shearlets are a relatively new and very effective multi-scale framework for signal analysis. Contrary to the traditional wavelets, shearlets are capable to efficiently capture the anisotropic information in multivariate problem classes. Therefore, shearlets can be seen as the valid choice for multi-scale ...

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. Webif t is an edge point and s = s 0 where s 0 is the normal orientation of the edge. If t is an edge and s = s 0, the decay is of the order a3/4. A similar behaviour holds if t is a corner point and s coincides with one of the normal directions of the corner, otherwise the decay is O(a9/4). For numerical implementation, it is useful to restrict ...
