WebDec 23, 2011 · A robust detail preserving anisotropic diffusion for speckle reduction in ultrasound images The proposed anisotropic diffusion can preserve the important structure information of the original image while reducing speckles. It is also less sensitive to the number of iterations.
WebIn this paper, we propose an anisotropic diffusion model involving fuzzy-based source for binarizing degraded document images, in which the diffusion term is response for edge-preserving smoothing and the source term is used to group intensity values of foreground and background pixels into two dominant modes separated by zero. WebThe robust statistical interpretation also provides a means for detecting the boundaries (edges) between the piecewise smooth regions in an image that has been smoothed with …
WebThe robust statistical interpretation also provides a means for detecting the boundaries (edges) between the piecewise smooth regions in an image that has been smoothed with anisotropic diffusion. Additionally, we derive a relationship between anisotropic diffusion and regularization with line processes. WebSep 1, 2005 · The anisotropic diffusion flow is applied to a probability image, obtained either from t-map statistics or via Bayes rule, and this information diffusion technique can be …
WebJan 19, 2024 · In this paper, we aim to propose a flexible and adaptive fourth-order diffusion PDE model associated with an efficient and robust contextual discontinuity indicator based on the bilateral kernel for image noise removal. Unlike existing models mentioned above, the merits of this paper are:
Web6 Conclusions. Anisotropic diffusion is an effective precursor to edge detection. The main benefit of anisotropic diffusion over isotropic diffusion and linear filtering is edge preservation.
