A New Edge-holding Algorithm of Image Interpolation
一种保持边缘特征的图像插值方法

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.
