Edge enhancement techniques based on minimum eigen values of the image pixels

Abstract EN

In this paper, a modify minimum Eigen values technique is introduced to detect edge points and outline the boundaries of objects within an image.

The presented edge method is performed by utilizing 3 × 3 and 5 × 5 windows, and counting the eigenvalues within each.

The minimum Eigen value then adopted to replace the window's center which finally produces an image.

Two types of image samples were used to test the propused method.

Sobel type of edge detection then was applied and the results were better in edge detection obviously.
