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

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

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

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

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

INTRODUCTION
function by decomposing it into a weighted sum of much simpler sinusoidal component functions sometimes referred to as normal Fourier modes, or simply modes for short. The weights, or coefficients, of the modes, are a one-to-one mapping of the original function. These modal coefficients are sometimes themselves confusingly referred to as modes for brevity, especially in physics literature. Fourier series serve many useful purposes, as manipulation and conceptualization of the modal coefficients are oft ....etc

Isolation and Spectral Characterization of Chlorophyll-Protein Complexes of Chloroplast Thylakoid Membranes
Introduction
In the undergraduate biology laboratory, labs on photosynthesis ordinarily fall into a small
number of categories:
1. measurement of the overall process of photosynthesis by carbon dioxide uptake or
oxygen evolution
2. measurement of the Hill reaction (the light driven reduction of an exogenous dye with
electrons from water) in isolated chloroplasts
3. pigment analysis by thin-layer or paper chromatography
