摘 要
提出了一种利用双三次样条曲面插值的方法,对图像进行放大处理,并在插值的同时考虑了边缘处的切矢及插值点位置的调整,从而保持了图像的边缘特征。实验结果表明,用该方法进行图像放大,可以得到很好的效果。

A New Edge-holding Algorithm of Image Interpolation

()

Abstract
In this paper a new image interpolation algorithm is proposed.Bicubic spline interpolation method is used in the algorithm to modify the image scale.The algorithm also considers tangent vector of the edge and position revision of the interpolation point.Thus the edge propert is maintained.The experiment results show that scaled image processed with proposed algrithm is of good quality.
