Spatial Correlation

Face Recognition Using Sign Only Correlation

In this work we examine a face recognition system based on advanced correlation filters. A thorough theoretical design analysis of, Minimum Average Correlation Energy (MACE) filters and Optimum Trade-off Synthetic Discriminant Function (OTSDF) also commonly known as Optimal Trade-off Filter (OTF) is provided. In practice one of the major computational aspects in the correlation filter design is...

Robust image registration by increment sign correlation

A novel and robust statistic as a similarity measure for robust image registration is proposed. The statistic is named as Increment Sign Correlation because it is based on average evaluation of incremental tendency of brightness in adjacent pixels. It is formalized to be a binary distribution or a Gaussian distribution for a large image size through statistical analysis and modeling. By utilizi...

Bayesian Analysis of Survival Data with Spatial Correlation

Often in practice the data on the mortality of a living unit correlation is due to the location of the observations in the study‎. ‎One of the most important issues in the analysis of survival data with spatial dependence‎, ‎is estimation of the parameters and prediction of the unknown values in known sites based on observations vector‎. ‎In this paper to analyze this type of survival‎, ‎Cox...

Spatial Correlation Testing for Errors in Panel Data Regression Model

To investigate the spatial error correlation in panel regression models, various statistical hypothesizes and testings have been proposed. This paper, within introduction to spatial panel data regression model, existence of spatial error correlation and random effects is investigated by a joint Lagrange Multiplier test, which simultaneously tests their existence. For this purpose, joint Lagrang...
