ABSTRACT
The world might have been reaching new heights in technology, man might have made artificial residential environment in outer space. But all this will end up to one primary objective. The aim of every human research is how to make life more comfortable and decrease the mortality of human beings.
For this reason a crucial visual study of animal tissue and environment is highly critical. The number of CMOS technology ....etc

COMPARISON OF ENERGY-BASED ENDPOINT DETECTORS FOR SPEECH SIGNAL PROCESSING
Accurate endpoint detection is a necessary capability for construction of speech databases from field recordings. In this paper we describe the implementation of two endpoint detection algorithms which use signal features based on energy and rate of zero crossings. We have made extensive use of object-oriented concepts and data-driven programming to make our code re-usable for a variety of applications, including speech recognition. A uniform user-i ....etc

Abstract


A multidisciplinary team of end users and suppliers has collaborated to develop a novel yet broadly enabling process for the design, fabrication and assembly of Micro-Opto-Electro-Mechanical Systems (MOEMS). A key goal is to overcome the shortcomings of the polysilicon layer used for fabricating optical components in a conventional surface micromachining process. These shortcomings include the controllability and uniformity of material stress that is a major cause of curvature and deformation in released microstructures. The appr ....etc

Abstract
This paper proposes a two-phase scheme for removing salt-and-pepper impulse noise. In the first
phase, an adaptive median filter is used to identify pixels which are likely to be contaminated by noise
(noise candidates). In the second phase, the image is restored using a specialized regularization method
that applies only to those selected noise candidates. In terms of edge preservation and noise suppression,
our restored images show a significant improvement compared to those restored by using just nonlinear
filters or r ....etc
