Detecting edge of medical image using statistical theory
Guo-Xin Kang · 2005
Consider the general case in which factors such as sampling error. So several independent the observed image consists of the .true image and a statistical tests are used as follows : Unimodality of a noise component. An edge detection approach devel- uniform and a Gaussian distribution, homogeneity oped for noisy image is described in this paper. It is tests of means, shortcut method, variance and based on the statistical theory with several tests. Ex- Cochran. (*' For each test, the critical values for ac- ample is given to demonstrate this technique. ceptance or rejection are preset.
