Binocular Disparity
Binocular disparity refers to the difference in image location of an object seen by the left and right human eye, eyes, resulting from the eyes’ horizontal separation (parallax). The brain uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis. In computer vision, binocular disparity refers to the difference in coordinates of similar features within two stereo images. A similar disparity can be used in rangefinding by a coincidence rangefinder to determine distance and/or altitude to a target. In astronomy, the disparity between different locations on the Earth can be used to determine various celestial parallax, and Earth's orbit can be used for stellar parallax. Definition Human eyes are horizontally separated by about 50–75 mm (interpupillary distance) depending on each individual. Thus, each eye has a slightly different view of the world around. This can be easily seen when alternately closing one eye while lookin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereopsis
Stereopsis () is the component of depth perception retrieved through binocular vision. Stereopsis is not the only contributor to depth perception, but it is a major one. Binocular vision happens because each eye receives a different image because they are in slightly different positions on one’s head (left and right eyes). These positional differences are referred to as "horizontal disparities" or, more generally, " binocular disparities". Disparities are processed in the visual cortex of the brain to yield depth perception. While binocular disparities are naturally present when viewing a real three-dimensional scene with two eyes, they can also be simulated by artificially presenting two different images separately to each eye using a method called stereoscopy. The perception of depth in such cases is also referred to as "stereoscopic depth". The perception of depth and three-dimensional structure is, however, possible with information visible from one eye alone, such as diffe ...

Running Disparity
In telecommunications, 8b/10b is a line code that maps 8-bit words to 10-bit symbols to achieve DC balance and bounded disparity, and at the same time provide enough state changes to allow reasonable clock recovery. This means that the difference between the counts of ones and zeros in a string of ''at least'' 20 bits is no more than two, and that there are not more than five ones or zeros in a row. This helps to reduce the demand for the lower bandwidth limit of the channel necessary to transfer the signal. An 8b/10b code can be implemented in various ways, where the design may focus on specific parameters such as hardware requirements, DC-balance, etc. One implementation was designed by K. Odaka for the DAT digital audio recorder. Kees Schouhamer Immink designed an 8b/10b code for the DCC audio recorder. The IBM implementation was described in 1983 by Al Widmer and Peter Franaszek. IBM implementation As the scheme name suggests, eight bits of data are transmitte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paired Disparity Code
In telecommunication, a paired disparity code is a line code in which at least one of the data characters is represented by two codewords of opposite disparity that are used in sequence so as to minimize the total disparity of a longer sequence of digits. A particular codeword of any line code can either have no disparity (the average weight of the codeword is zero), negative disparity (the average weight of the codeword is negative), or positive disparity (the average weight of the codeword is positive). In a paired disparity code, every codeword that averages to a negative level (negative disparity) is paired with some other codeword that averages to a positive level (positive disparity). In a system that uses a paired disparity code, the transmitter must keep track of the running DC buildup the running disparity and always pick the codeword that pushes the DC level back towards zero. The receiver is designed so that either codeword of the pair decodes to the same data bits. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Disparities
Health equity arises from access to the social determinants of health, specifically from wealth, power and prestige. Individuals who have consistently been deprived of these three determinants are significantly disadvantaged from health inequities, and face worse health outcomes than those who are able to access certain resources. It is not equity to simply provide every individual with the same resources; that would be equality. In order to achieve health equity, resources must be allocated based on an individual need-based principle. According to the World Health Organization, "Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". The quality of health and how health is distributed among economic and social status in a society can provide insight into the level of development within that society. Health is a basic human right and human need, and all human rights are interconnected. Thus, health must be discusse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Inequality
There are wide varieties of economic inequality, most notably income inequality measured using the distribution of income (the amount of money people are paid) and wealth inequality measured using the distribution of wealth (the amount of wealth people own). Besides economic inequality between countries or states, there are important types of economic inequality between different groups of people. Important types of economic measurements focus on wealth, income, and consumption. There are many methods for measuring economic inequality, the Gini coefficient being a widely used one. Another type of measure is the Inequality-adjusted Human Development Index, which is a statistic composite index that takes inequality into account. Important concepts of equality include equity, equality of outcome, and equality of opportunity. Whereas globalization has reduced global inequality (between nations), it has increased inequality within nations. Income inequality between nations peak ...

Male–female Income Disparity In The United States
The gender pay gap in the United States is a measure between the earnings of male and females in the workforce. When calculating the pay gap, non-adjusted versus adjusted pay gap is utilized. The adjusted pay gap takes into consideration the differences in hours worked, occupations chosen, education and job experience, whereas the non-adjusted pay gap is the overall difference of gross hourly earnings of males and females in the United States. The non-adjusted average female annual salary is around 80% of the average male salary, compared to 95% for the adjusted average salary. Statistics Women's median yearly earnings (which is used by the Census Bureau to calculate its gap includes bonuses, while the Bureau of Labor Statistics uses weekly earnings which does not) relative to men's rose rapidly from 1980 to 1990 (from 60.2% to 71.6%), and less rapidly from 1990 to 2000 (from 71.6% to 73.7%), from 2000 to 2009 (from 73.7% to 77.0%), and from 2009 to 2018 (from 77.0% to 81.1%). ...

Income Gender Gap
The gender pay gap or gender wage gap is the average difference between the remuneration for men and women who are working. Women are generally found to be paid less than men. There are two distinct numbers regarding the pay gap: non-adjusted versus adjusted pay gap. The latter typically takes into account differences in hours worked, occupations chosen, education and job experience. In the United States, for example, the non-adjusted average woman's annual salary is 79% of the average man's salary, compared to 95% for the adjusted average salary. The reasons link to legal, social and economic factors, and extend beyond " equal pay for equal work". The social factors include topics such as discrimination based on gender, the motherhood penalty vs. fatherhood bonus, parental leave, and gender norms. Additionally, the consequences of the gender pay gap surpass individual grievances, leading to reduced economic output, lower pensions for women, and fewer learning opportunities. T ...

International Inequality
International inequality refers to inequality between countries, as compared to global inequality, which is inequality between people across countries. International inequality research has primarily been concentrated on the rise of international income inequality, but other aspects include educational and health inequality, as well as differences in medical access. Reducing inequality within and among countries is the 10th goal of the UN Sustainable Development Goals and ensuring that no one is left behind is central to achieving them. Inequality can be measured by metrics such as the Gini coefficient. According to the United Nations Human Development Report 2004, the gross domestic product (GDP) per capita in countries with high, medium and low human development (a classification based on the UN Human Development Index) was 24,806, 4,269 and 1,184 PPP$, respectively (PPP$ = purchasing power parity measured in United States dollars).

Income Inequality In The United States
Income inequality in the United States is the extent to which income is distributed in differing amounts among the American population. It has fluctuated considerably since measurements began around 1915, moving in an arc between peaks in the 1920s and 2000s, with a 30-year period of relatively lower inequality between 1950 and 1980. The U.S. has the highest level of income inequality among its (post-)industrialized peers.United Press International (UPI), June 22, 2018"U.N. Report: With 40M in Poverty, U.S. Most Unequal Developed Nation"/ref> When measured for all households, U.S. income inequality is comparable to other developed countries before taxes and transfers, but is among the highest after taxes and transfers, meaning the U.S. shifts relatively less income from higher income households to lower income households. In 2016, average market income was $15,600 for the lowest quintile and $280,300 for the highest quintile. The degree of inequality accelerated within the t ...

Wealth Inequality In The United States
Wealth inequality in the United States is the unequal distribution of assets among residents of the United States. Wealth commonly includes the values of any homes, automobiles, personal valuables, businesses, savings, and investments, as well as any associated debts. Although different from income inequality, the two are related. Wealth is usually not used for daily expenditures or factored into household budgets, but combined with income, it represents a family's total opportunity to secure stature and a meaningful standard of living, or to pass their class status down to their children. Moreover, wealth provides for both short- and long-term financial security, bestows social prestige, contributes to political power, and can be leveraged to obtain more wealth. Hence, wealth provides mobility and agency—the ability to act. The accumulation of wealth enables a variety of freedoms, and removes limits on life that one might otherwise face.

Disparity (ecology)
A guild (or ecological guild) is any group of species that exploit the same resources, or that exploit different resources in related ways. It is not necessary that the species within a guild occupy the same, or even similar, ecological niches. Details Guilds are defined according to the locations, attributes, or activities of their component species. For example, the mode of acquiring nutrients, the mobility, and the habitat zones that the species occupy or exploit can be used to define a guild. The number of guilds occupying an ecosystem is termed its ''disparity''. Members of a guild within a given ecosystem could be competing for resources, such as space or light, while cooperating in resisting wind stresses, attracting pollinators, or detecting predators, such as happens among savannah-dwelling antelope and zebra. A guild does not typically have strict, or even clearly defined boundaries, nor does it need to be taxonomically cohesive. A broadly defined guild will almost alway ...
