Passive Millimeter-wave Image Restoration using Maximum Entropy Method with
Passive millimeter-wave (PMMW) image have an inherently poor resolution and highly blurred due to limited aperture dimension and the consequent diffraction limits thus requiring specialized sophisticated restoration algorithm before the image can be used for any useful purposes. In recent years many powerful algorithms based on Bayesian statistical concept are developed. These algorithms are no...
متن کاملMammographic image restoration using maximum entropy deconvolution.
An image restoration approach based on a Bayesian maximum entropy method (MEM) has been applied to a radiological image deconvolution problem, that of reduction of geometric blurring in magnification mammography. The aim of the work is to demonstrate an improvement in image spatial resolution in realistic noisy radiological images with no associated penalty in terms of reduction in the signal-t...
متن کاملRestoration of Degraded Images with Maximum Entropy
Images recorded in electronic or photographic media are often degraded due to system imperfections such as diffraction effects, optical system aberrations, camera and/or object motions, defocussing, or atmospheric turbulences. In addition to these blurring effects, the recorded image is usually corrupted by various random noise effects such as the randomness of the film grain, photoelectric eff...
متن کاملMaximum Entropy Based Restoration of Arabic Diacritics
Short vowels and other diacritics are not part of written Arabic scripts. Exceptions are made for important political and religious texts and in scripts for beginning students of Arabic. Script without diacritics have considerable ambiguity because many words with different diacritic patterns appear identical in a diacritic-less setting. We propose in this paper a maximum entropy approach for r...
