EDGE ENHANCEMENT TECHNIQUES BASED ON MINIMUMEIGEN VALUES OF THE IMAGE PIXELS

Abstract

In this paper, an 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.
