The paper describes a new image processing for a non-photorealistic rendering. The algorithm is based on a random generation of gray tones and competing statistical requirements. The gray tone value of each pixel in the starting image is replaced selecting among randomly generated tone values, according to the statistics of nearest-neighbor and next-nearest-neighbor pixels. Two competing condit...

An efficient technique is presented for obtaining dense stereo correspondence using a new adaptive Block Matching technique. First, one of the color stereo images (e.g., the left) is segmented into chromatic and achromatic regions using perceptual attributes in the HSI color space. Then the Block Matching technique is applied to the stereo images using adaptive similarity measures. The results ...

The blending of defective texture with the ambience texture results in camouflage. The gray value or color distribution pattern of the camouflaged images fails to reflect considerable deviations between the camouflaged object and the sublimating background demands improved strategies for texture analysis. In this research, we propose the implementation of an initial enhancement of the image tha...

Winter 2010 bons of green meandering through a largely gray landscape. They form an interconnected network of “green infrastructure” that can be integrated into “gray infrastructure.” The tools described here focus on trees and parks because they are the largest structural elements and responsible for most benefits and costs. Their value is equal to the net benefits that members of society obta...

Smoothness constraints have been used to f a c i l i tate the estimation of displacement vector f i e lds . Differing from HORN and SCHUNCK 81 who employ a general smoothness requirement, this contribution reports an analysis of an "oriented smoothness" requirement: a change in the displacement vector f i e ld is only constrained in the direction perpendicular to the characteristic gray value v...

| A procedure for estimating the joint probability density function (pdf) of T 1 , T 2 , and proton spin density (P D) for gray matter (GM), white matter (WM), and cerebrospinal uid (CSF) in the brain is presented. The pdf's have numerous applications, including the study of tissue parameter variability in pathology and across populations. The procedure requires a multispectral, spin echo magne...

A new psychophysical methodology is introduced, histogram contrast analysis, that allows one to measure stimulus transformations, f, used by the visual system to draw distinctions between different image regions. The method involves the discrimination of images constructed by selecting texture micropatterns randomly and independently (across locations) on the basis of a given micropattern histo...

OBJECTIVE To assess the value of MicroPure, a new ultrasound image processing technique, in identifying microcalcifications (formed by monosodium urate crystals) in the first metatarsophalangeal joints attacked by gout compared to gray-scale ultrasound images. MATERIALS AND METHODS Thirty-six patients who fulfilled the study inclusion criteria underwent gray-scale ultrasound and MicroPure exa...

Image captured under various environment conditions with low contrast results in visual deterioration. To enhance the contrast of images a number of techniques have been proposed over the years. Histogram equalization is one of those methods which could be used for this purpose. For the contrast enhancement purpose histogram equalization (HE) attempts reduction in the number of gray levels. Con...
