Wavelet-based Image Enhancement using Nonlinear Anisotropic Diffusion
Many sensing techniques and image processing applications are characterized by random noisy, or corrupted, image data. Nonlinear Anisotropic diffusion is a popular, and theoretically well understood, technique for enhancing such images.Diffusion approaches however require the selection of an “edge stopping” function, the definition of which is typically adhoc. Many recent techniques for digital...
متن کاملAn anisotropic diffusion filter based on multidirectional separability
Extracting tongue contour from high noised ultrasound image is a key issue of observing speech production procedure. Anisotropic diffusion has been widely used in reducing speckle noise of ultrasound images but it is not very effective in preserving edges and tends to blur them. Hence the blurred edges hamper the succeeding contour-based pattern analysis or modeling. In this study, we modify th...
متن کاملWavelet Oriented Anisotropic Diffusion in Image Enhancement
In this paper, we introduce a new anisotropic diffusion partial differential equation, in which the gradients is adjusted by the wavelet transform of the solution. The new model adopts wavelet transform theory so that the numerical implementation is more effective and accurate. The existence and uniqueness of the solutions are proved. The equation can formulate image enhancement and the numeric...
متن کاملHybrid regularizers-based adaptive anisotropic diffusion for image denoising
To eliminate the staircasing effect for total variation filter and synchronously avoid the edges blurring for fourth-order PDE filter, a hybrid regularizers-based adaptive anisotropic diffusion is proposed for image denoising. In the proposed model, the [Formula: see text]-norm is considered as the fidelity term and the regularization term is composed of a total variation regularization and a f...
متن کاملPolSAR anisotropic diffusion filter with a refined similarity measure and an adaptive fidelity constraint
The presence of speckle complicates the tasks of interpreting and analysing polarimetric synthetic aperture radar (PolSAR) images. The nonlinear anisotropic diffusion (AD) method has been found to perform well in removing image noise. In this article, we propose a new ADmethod for PolSAR speckle reduction. An iterative refinement method is employed to measure the similarity between pixels and c...
