Detecting Patient Motion in SPECT Imaging Using Stereo Optical Cameras



1. Introduction
Patient motion causes many problems in SPECT imaging, such as blur and other motion artifacts. If patient motion is excessive, it may be necessary to repeat an acquisition, with consequent cost and inconvenience. Previous approaches to motion detection relied on inconsistency checks or motion tracking, or were limited to rigid body parts, such as the head. The goal of this work is to des ....etc

WEARABLE REAL-TIME STEREO VISION FOR THE VISUALLY IMPAIRED

Abstract
Visually impaired find their navigation difficult as they often lack the needed information for bypassing obstacles and hazards. Electronic Travel Aids (ETAs) are devices that use sensor technology to assist and improve the blind user’s mobility in terms of safety and speed. Modern ETAs does not provide distance information directly and clearly. This paper proposes a method for determining distance using a stereo matching method to help blin ....etc

Abstract
We present a novel multi-view stereo method designed
for image-based rendering that generates piecewise planar
depth maps from an unordered collection of photographs.
First a discrete set of 3D plane candidates are computed
based on a sparse point cloud of the scene (recovered by
structure from motion) and sparse 3D line segments reconstructed
from multiple views. Next, evidence is accumulated
for each plane using 3D point and line incidence and
photo-consistency cues. Finally, a piecewise planar depth
map is recove ....etc

This protocol controls telephony gateways from external call control elements called media gateway controllers or call agents. Converting among the audio signals carried on telephone circuits and data packets carried over the Internet or over other packet networks is done by telephony gateway. According to the call control architecture assumption of the MGCP the call control intelligence is outside the gateways and handled by external call control elements and these call control elements, or Call Agents, will synchronize with each other to send ....etc

In the output stages of most broadcastreceivers and some amplifiers,there is a limit up to which maximumpower can be developed withoutdistortion. In the widely acceptedoutput circuit, two output transistorsare connected in series between thepositive and ground and biasing is adjustedso that each transistor gets halfthe supply voltage.The circuit presented here is asimple audio amplifier for a personalstereo system. In this, supply voltageto each transistor can be enhanced toproduce a larger output. The audiodriver transformer drives the transis ....etc

The Megaco protocol is used between elements of a physically decomposed multimedia gateway and is the result of cooperative efforts of the IETF and the ITU-T Study Group 16. The protocol definition of this protocol is common text with ITU-T Recommendation H.248. There are no functional differences from a system view between a decomposed gateway, with distributed sub-components potentially on more than one physical device, and a monolithic gateway such as described in H.246 . The Packet network interfaces may include IP, ATM or possibly ot ....etc

IMPLEMENTATION OF STEREO SOUND ENHANCEMENT ON FPGA


INTRODUCTION
1.1 Background
In digital media, quality of stereo sound is more enjoyable than mono sound. Stereo sound is produced from more than one channel. There are several ways to mix two mono sound channels to produce stereo sound. One method of stereo sound enhancement is achieved by widening the stereo sound filed, so listener can enjoy clear and noiseless sound with great feeling. This stereo ....etc

In the today's cyber world, we are largely dependent on computers. With the advancement of technology and complexity of computers, the need for massive storage is mandatory. Hard disks have been a major storage media for the past several years. Hard disks continue to shrink in size, gain increased storage capacity and increased transfer speeds.

The focus of development has been on increasing the density. But this may ultimately lead to saturation to atomic levels one day. Hence in this paper, on the basis of domain theory, different states h ....etc
