The measurement of image disparity is a fundamental precursor to binocular depth estimation. Recently, Jenkin and Jepson (in Computational Processes in Human Vision (V. Pylyshyn, Ed.), Ablex, New Jersey, ) and Sanger (Biol. Cybernet, 59,–) described promising methods based on the output phase behavior of bandpass Gabor we discuss further Cited by: CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The measurement of image disparity is a fundamental precursor to binocular depth estimation.

Recently, Jenkin and Jepson () and Sanger () described promising methods based on the output phase behaviour of band-pass Gabor filters.

Here we discuss further justification for such techniques based on the stability. Abstract. The measurement of image disparity is a fundamental precursor to binocular depth estimation. Recently, Jenkin and Jepson () and Sanger () described promising methods based on the output phase behaviour of band-pass Gabor filters.

Phase-based disparity measurement. In this case, depth estimation is mainly based on the measurements of binocular disparities defined as the local shift of the relative spatial location of images of the same object on the retinae of the two eyes.

The problem of determining binocular disparity has an elegant formulation in the frequency domain, in relation to the so-called phase. Abstract. Phase differencing techniques have been proven to be fast and robust methods for estimating disparity between two views.

This disparity estimation depends on the quality of the local phase information which is a response of carefully designed frequency. Abstract: Three dimensional (3D) shape-measurement systems combining fringe projection and stereo vision utilize phase for dense stereo matching.

However, projection of orthogonal fringe patterns and computation of curved epipolar lines due to lens distortion has made traditional phase-based stereo matching time-consuming. Stereoscopic depth analysis by means of disparity estimation has been a classical topic of computer vision, from the biological models of stereopsis [1] to the widely used techniques based on correlation or sum of squared differences [2].

Most of the recent work on this topic has been devoted to the phase-based techniques, developed because of their superior performance and better theoretical. This chapter explores critical issues related to the measurement of health equity.

It notes that without reliable data on disparities in health, policy makers and populations are less equipped to demand change and monitor progress. The chapter provides a comprehensive approach to the measurement of inequity. It outlines five basic considerations in the choice of health measures, highlighting.

measure disparities in health and to monitor trends in disparities. This report discusses six significant issues that should be considered in measuring disparities: first, the selection of a reference point from which to measure disparity (5); second, measurement of disparity in absolute or in relative terms (5); third, measurement.

Commissioned Paper: Healthcare Disparities Measurement.: measure of absolute health disparity, and either the Relative Index of Inequality (RII) or the Relative Concentration Index (RCI) as a measure of relative disparity.

When comparisons across multiple groups that have no natural ordering (e.g., race/ethnicity) are needed, we recommend the Between-Group Variance (BGV) as a summary of absolute. unique measure of disparity for a given x position; rather all possible responses are represented.

Classic correla- tion techniques choose peaks in the disparity for a given x position as the true disparity. The correlation-based algorithm produces a large broad peak over a wide range of disparities.

BACKGROUND AND DEVELOPMENT OF THE HEALTH DISPARITIES CALCULATOR. A Healthy People goal was to eliminate health disparities.3 This goal, which was expanded in Healthy People to “achieve health equity, eliminate disparities, and improve the health of all groups,” raised the dilemma: how can we define and measure disparities.

The National Center for Health Statistics. Rights, Deprivation, and Disparity: Essays in Concepts and Measurement: Business Development Books @ Magnetic Sensors Hall-Effect Sensors   There is a debate about which measure (absolute or relative) to use to evaluate progress towards reducing health disparities.

Measuring the absolute disparity and the size of the two population groups provide a method to estimate the population health burden of disparities between the two groups (Harper & Lynch). poverty measurement worldwide and sketches a road to improving country practices while achieving greater comparability within and across countries.

It is hoped that this book will serve as the basis for formulating national, regional and international statistical programs to strengthen the capacity in member countries to collect and analyze data. Rights, Deprivation, and Disparity book.

The material is divided into four parts.This paper proposes a method for phase difference measurement based on the principle of progressive phase shift (PPS).

A phase difference measurement system based on PPS and implemented in the FPGA chip is proposed and tested. In the realized system, a fully programmable delay line (PDL) is constructed, which provides accurate and stable delay, benefitting from the feed-back structure of the.
