【摘要】 为了提高图像的缩放质量,提出一种自适应图像缩放算法。当原图像像素点处于边缘区域时,沿Sobel算子确定的边缘方向进行自适应插值,当原图像像素点处于非边缘区域时,采用双线性插值法进行插值。实验结果表明,Sobel算子可有效获得图像边缘特性,该算法能通过较低的运算复杂度获得较好的图像缩放质量。更多还原

【Abstract】 In order to enhance image scaling quality,this paper proposes a self-adaptive image scaling algorithm.When pixel point of original image is in the edge area,the interpretation is carried adaptively along the edge direction obtained by Sobel operator.For the non-edge area,it uses bilinear interpolation algorithm.Experimental result shows that Sobel operator can get the edge characteristics efficiently,and this algorithm can get high-quality scaled images with lower complexity.更多还原
