摘要

图像缩放是图像处理的重要组成部分。为了保护图像的边缘特征，本文提出了一种改进的边缘自适应图像缩放算法，该算法主要采用简单的定向边缘检测器将图像划分为四种图像块，然后沿边缘方向进行自适应插值。实验结果表明，该算法能够生成边缘保存良好、计算复杂度低的高质量图像。

An improved edge-adaptive image scaling algorithm

Image scaling is an important part of image processing. In order to protect edge characteristics of images, this paper proposes an improved edge-adaptive image scaling algorithm, in which the image is mainly divided into four kinds of image blocks with simple directional edge detector, and interpolation is then adaptively carried out along edge direction. Our experiment shows that the proposed algorithm can produce high-quality images with well-preserved edge and low computational complexity.
