This paper reviews diffraction tomography as it applies to electromagnetic and acoustical
imaging. We have discussed the various approximations that are used and shown their …

An infrared image contrast enhancement algorithm based on a discrete stationary wavelet
transform (DSWT) and non-linear gain operator is proposed. Having implemented DSWT on …

The weighting filter is a new non-linear algorithm designed to reduce speckle noise in
synthetic aperture radar (SAR) images and is presented in this article. Intrinsic similarities …

The Automatic Teller Machine (ATM) plays an important role in the modern economy. It
provides a fast and convenient way to process transactions between banks and their …

Segmentation is the low-level operation in image processing which partitions an image into
disjoint and homogeneous regions. We consider segmentation of color images, a task which …

When repetitive structures such as line-gratings or dot-screens are superposed, a new
pattern may become clearly visible in the superposition, although it does not exist in any of …

The vision processor (VP) and vision controller (VC), two integrated products dedicated to
video compression, are discussed. The chips implement the P* 64, JPEG, and MPEG image …

Digital x-ray images are routinely processed to enhance diagnostic information and to
suppress irrelevant detail, and also to extract quantitative information. The basic concepts …
