An image through the digitization process is referred to as a digital image. The quality of the
digital image may be degenerating due to interferences on the acquisition, transmission …

Noisy or corrupt images are characterized by poor contrast and ill-defined ridges and
valleys. Such images need to be enhanced using suitable image enhancement techniques …

This research paper presents an efficient hybrid framework for the enhancement of X‐ray
images using the DWT (discrete wavelet transform), Gaussian, and Wiener filters. Digital X …

The concept of the tropical algebra was first introduced to solve problems in mathematical
economy such as optimization and approximation problems. In this paper, the concept of …

Noise is the information damage that may occur in the image due to the changes in
information during the transmission process. In order to overcome these problems, it is …

A novel idea of using median deviation parameter in estimating the noise in the images is
proposed and successfully applied to both gray level as well as color images. The median …

BACKGROUND: Airport security is still a main concern for assuring passenger safety and
stopping illegal activity. Dual-energy X-ray Imaging (DEXI) is one of the most important …

Research displays an extensive investigation for different factual statistical estimates and
their practical implementation in picture handling with various noises and filter channel …

In this paper, we introduce a novel edge directed image detail preserving impulse noise
removal algorithm. Our approach is based on local image directionality features. Local edge …

In many image and video processing algorithms, pre-processing filters are the first and most
important step. These filters reduce the noise present in the images, preserving the required …
