A Non-Parametric Approach to Visual Correspondence
نویسندگان
چکیده
We describe a method for computing visual correspondence based on the local ordering of intensities. Ordering information is robust to outliers and invariant to mono-tonic intensity distortions such as image gain. Our approach is based on non-parametric measures of association but also accounts for the spatial variation of disparities. We describe some of the mathematical properties of our algorithms, and demonstrate their utility on both synthetic and real imagery with ground truth. These methods are extremely eecient, and have been used for video-rate stereo and motion.

Introduction of Human Development Index (HDI) by UNDP in early 1990 followed a surge in use of non-parametric and parametric indices for measurement and comparison of countries performance in development, globalization, competition, well-being and etc. The HDI is a composite index of three indicators. Its components are to reflect three major dimensions of human development: longevity, knowledg...
متن کاملNon - parametric Local Transforms forComputing Visual
We propose a new approach to the correspondence problem that makes use of non-parametric local transforms as the basis for correlation. Non-parametric local transforms rely on the relative ordering of local intensity values, and not on the intensity values themselves. Correlation using such transforms can tolerate a signiicant number of outliers. This can result in improved performance near obj...

متن کاملA new non-parametric approach for suppliers selection
In this paper we propose a simple non-parametric model for multiple crite-ria supplier selection problem. The proposed model does not generate a zeroweight for a certain criterion and ranks the suppliers without solving the modeln times (one linear programming (LP) for each supplier) and therefore allowsthe manager to get faster results. The methodology is illustrated using anexample.
متن کاملA comparison of parametric and non-parametric methods of standardized precipitation index (SPI) in drought monitoring (Case study: Gorganroud basin)
The Standardized Precipitation Index (SPI) is the most common index for drought monitoring. Although the calculation of this index is usually done by using the gamma distribution fitting of precipitation data, studies have shown that for accurate monitoring of drought, the optimal distribution of precipitation in each month should be determined. On the other hand, in non-stationary time series,...
