Fuzzy Anisotropic Smoothing of Scalar Images

چکیده

This study suggests a fuzzy anisotropic smoothing technique on scalar (grayscale) images using partial differential equations (PDEs) and fuzzy sets. This technique preserves the image details such as edges while noise is being reduced. The PDE and fuzzy rule based techniques are employed in approximation of smoothing coefficients calculated based on structure and noisiness information. Utilizing multiple tools constitutes the advantages of the proposed technique compared to the others. The results reveal that this technique can perfectly be used in denoising images in which fine details are definitely to be preserved during the smoothing operation.

Introduction to a simple yet effective Two-Dimensional Fuzzy Smoothing Filter

Annihilation or reduction of each kind of noise blended in correct data signals is a field that has attracted many researchers. It is a fact that fuzzy theory presents full capability in this field. Fuzzy filters are often strong in smoothing corrupted signals, whereas they have simple structures. In this paper, a new powerful yet simple fuzzy procedure is introduced for sharpness reduction in ...

Anisotropic vector diffusion in image smoothing

Anisotropic diffusion has been widely used in image processing for its efficiency of smoothing the noisy images while preserving the sharp edges. In this paper we will explore a general version of anisotropic diffusion schemes for vectorvalued images, based on the polar-coordinate representation of the vectors. As an example, we will apply our method to color images and show its ability of edge...

Fuzzy anisotropic diffusion for speckle filtering

An anisotropic diffusion filter contoled by fuzzy rules is presented. The proposed filter is based in the Perona-Malik technique, using a fuzzy reasoning to calculate de diffusion coefficient which controls the whole diffusion. The method has the advantage that it can be used for both smoothing and noise cleaning, as well as edge enhancement. This new aproach also allows ut to model the diffusi...

Bilateral Filtering and Anisotropic Diffusion: Towards a Unified Viewpoint

bilateral filtering, anisotropic diffusion, adaptive smoothing, denoising Bilateral filtering has recently been proposed as a noniterative alternative to anisotropic diffusion. In both these approaches, images are smoothed while edges are preserved. Unlike anisotropic diffusion, bilateral filtering does not involve the solution of partial differential equations and can be implemented in a singl...
