Line detection using IIor~gh transform is one of the robust image processing methods for noisy images. Hut Hough t,ransform has a problem whose computation cost is very large in general. In order to ease this problem, many high-speed algorithms had been proposed. In this paper, we propose a new high-speed algorithm called MRHT (Multiple Randomized Hough Transform) which combines randomized edge...

The suprachiasmatic nucleus (SCN) is a central pacemaker in mammals, driving many endogenous circadian rhythms. An important pacemaker target is the regulation of a hormonal message for darkness, the circadian rhythm in melatonin synthesis. The endogenous clock within the SCN is synchronized to environmental light/dark cycles by photic information conveyed via the retinohypothalamic tract (RHT)...

The track-before-detect (TBD) methodologies jointly process more consecutive scans and show superior detection performance for the low signal-to-noise ratio (SNR) targets over the conventional methods. A TBD algorithm based on improved Randomized Hough Transform for dim target detection is proposed in this paper. This algorithm uses the sequence numbers of scans to make sure that the point pair...

The remarkable increase in chondrocyte volume is a major determinant in the longitudinal growth of mammalian bones. To permit a detailed morphological study of hypertrophic chondrocytes using standard histological techniques, the preservation of normal chondrocyte morphology is essential. We noticed that during fixation of growth plates with conventional fixative solutions, there was a marked m...

Context. Polarized dust emission can be used as a probe for magnetic fields at different scales. In particular, the analysis of relative orientation between density structures and field projected on plane sky provide information role in shaping structure molecular clouds. Aims. The has been investigated using methods. Our goal is to explicitly compare two them: Rolling Hough Transform (RHT) gra...

Wheat is the main crop and often a strategic crop in many European countries. From a historical perspective, we describe the transfer of "reduced height genes" (Rht genes) from Japanese wheat varieties to wheat varieties in Europe and their influence on the increase of the total wheat production in the last century. Historic pathways of Rht genes were influenced directly or indirectly by wheat ...

It has been demonstrated that resting coronary vascular resistance is elevated with chronic hypertension and concomitant cardiac hypertrophy. The present study employed a model of 6-week, one-kidney, one wrapped Page hypertension to determine if the ability of the heart to match an increase in oxygen demand with an increase in oxygen supply (coronary blood flow) is impaired, and to determine if...

INTRODUCTION Rapid HIV testing (RHT) greatly increases the proportion of clients who learn their test results. However, existing studies have not examined the adoption and implementation of RHT in programs treating persons with substance use disorders, one of the population groups at higher risk for HIV infection. METHODS We examined 196 opioid treatment programs (OTPs) using data from the 20...

Abstract Genetic susceptibility to late maturity alpha-amylase (LMA) in wheat ( Triticum aestivum L.) results increased activity mature grain when cool conditions occur during maturation. Farmers are forced sell with elevated at a discount because it has an risk of poor end-product quality. This problem can result from either LMA or preharvest sprouting, germination on the mother plant rain occ...
