Abstract

The magnification of an image is general purposed method for image processing. The typical conventional methods for image magnification are the bi-liner-interpolation and the cubic-convolution. These methods often generate a blurred and unclear image. We proposed a new magnification method by using the gradient information by pixel. And this paper proposes an improved magnification method by using the gauss function and the gradient information in wide pixels area. The experimental results show that the clear magnified images were generated.
