— Video-surveillance and traffic analysis systems can be heavily improved using vision-based techniques to extract, manage and track objects in the scene. However, problems arise due to shadows. In particular, moving shadows can affect the correct localization, measurements and detection of moving objects. This work aims to present a technique for shadow(More)
3D Television enhances viewing experience by adding visual impact to any scene. Generating stereoscopic content from the vast collection of already existing 2D material is less expensive and less time consuming than creating 3D material using stereoscopic cameras. Depth Image Based Rendering (DIBR) is one of the various approaches for 2D to 3D video(More)
The calmodulin content of the yeast and mycelial phases of Ceratocystis ulmi was determined by radioimmunoassay. Calmodulin levels increased at the G1-S boundary of the cell cycle, coinciding with the first visible appearance of buds or germ tubes. However, in both phases the cellular calmodulin levels were equivalent. No differential synthesis was observed.
In this paper, the algorithm is developed by combining advantages of the median filters for filtration of noisy pixels with noise detection step. The algorithm works well for suppressing impulse noise with noise density ranging from 10 to 70% while preserving image details. The proposed algorithm is based on the two schemes:- 1) Impulse noise detection(More)
In this paper a novel method for effectively denoising the extremely corrupted image by fixed value impulse noise using robust estimation based filter is proposed. The proposed algorithm classifies the pixels of localized window in to " corrupted " or " uncorrupted " and removes only corrupted pixels by robust estimation or by mean of the processed(More)
The present study was carried out in B.A.R.C. Hospital Blood Bank over a span of five years, and includes 2734 donors. All the bags were screened for HIV, HBsAg, HCV and VDRL and the plasma in the pilot tubes of the blood bags was observed to detect any abnormality in color. In 27 cases plasma was found to be icteric and liver function tests were carried(More)
