چکیده

This paper presents a frequency domain degraded image restoration practical method. We call it practical wiener filter. Using this filter, the value for K parameter of wiener filter is determined experimentally that is so difficult and time consuming. Furthermore, there is no any absolute remark to claim that the obtained images by restoration process are the best could be possible. In order to find a solution for this problem, we use genetic algorithm to obtain the best value for K. Therefore, this paper presents an image restoration method which employs a Computer Aided Design (CAD) to image restoration where there is no need to original safe image. It means that, degraded image is as input and restored one is as output of CAD. Simulation results confirm that this method is successful and has executive ability in most applications.

Image Restoration by Variable Splitting based on Total Variant Regularizer

The aim of image restoration is to obtain a higher quality desired image from a degraded image. In this strategy, an image inpainting method fills the degraded or lost area of the image by appropriate information. This is performed in such a way so that the obtained image is undistinguishable for a casual person who is unfamiliar with the original image. In this paper, different images are degr...

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...

Applying the Algorithm of Lagrange Multipliers in Digital Image Restoration ∗

A method for digital image restoration, based on the algorithm of Lagrange multipliers, has many practical applications. We apply the method to remove blur in an image caused by uniform linear motion. This method assumes that linear motion corresponds to an integral number of pixels. The main contributions of the method were found on the Improvement in Signal to Noise Ration (ISNR) that have be...

Image Analysis and Partitioning for FPGA Implementation of Image Restoration

It is almost safe to state that there are no applications where images are acquired or processed which do not have active or potential work on image restoration. In the center of work lies an FPGA implementation of an iterative image restoration algorithm. Hardware design for the image restoration algorithm and estimations on the performance of the FPGA implementation is presented. During the r...

PSO-Optimized Blind Image Deconvolution for Improved Detectability in Poor Visual Conditions

Abstract: Image restoration is a critical step in many vision applications. Due to the poor quality of Passive Millimeter Wave (PMMW) images, especially in marine and underwater environment, developing strong algorithms for the restoration of these images is of primary importance. In addition, little information about image degradation process, which is referred to as Point Spread Function (PSF...
