Abstract

This paper proposes a new method of image enhancement. Firstly, the image is sharpened by Laplace operator, and then the low frequency part of the image is removed by non-sharpening filtering, the high frequency part of the image is retained which will obtain a high pass image. At last the high filtering is made to enhance the image. The method is applied to numerical experiments. Experimental results show that proposed method can not only remove the low frequency part of the image, preserve the high frequency part of the image, but also improve the definition of the image. It is an effective method of image enhancement.
