Image Restoration Using A PDE-Based Approach

 Image restoration is an essential preprocessing step for many image analysis applications. In any image restoration techniques, keeping structure of the image unchanged is very important. Such structure in an image often corresponds to the region discontinuities and edges. The techniques based on partial differential equations, such as the heat equations, are receiving considerable attention i...

A New Iterative Fuzzy-Based Method for Image Enhancement (RESEARCH NOTE)

This paper presents a new filtering approach based on fuzzy-logic which has high performance in mixed noise environments. This filter is mainly based on the idea that each pixel is not allowed to be uniformly fired by each of the fuzzy rules. In the proposed filtering algorithm, the rule membership functions are tuned iteratively in order to preserve the image edges. Several test experiments we...

Digital image restoration by Wiener filter in 2D case

Modern digital technology has made it possible to manipulate multi-dimensional signals with systems that range from simple digital circuits to advanced parallel computers. The goal of this manipulation can be divided into three categories: • Image Processing image in! image out. • Image Analysis image in ! measurements out. • Image Understanding image in! high-level description out. Further, we...

A Brief Review of Image Restoration Techniques

Image restoration is an essential issue in high level image processing which deals with recovering of an original and sharp image using a degradation and restoration model. Through image acquisition process degradation occurs. Image restoration is used to estimate the unique image from the degraded data. The degradations include half toning, dithering and security watermarks. An iterative image...
