Comparison of Edge Detection using Linear Rank Tests in Images
영상에서 선형순위검정법을 이용한 에지검출 비교
Abstract
In this paper we propose three nonparametric tests such as Wilcoxon test, Median test and Van der Waerden test, based on linear rank statistics for detecting edges in images. The methods used herein are based on detecting changes in gray-levels obtained using an edge-height parameter between two sub-regions in a 5
