摘要/Abstract

摘要： 图像旋转算法采用的插值方法存在不足,容易出现“锯齿”形边缘和模糊的现象,改变了图像的表示模型,为此提出了平面插值和球面插值相结合的图像插值方法,从而避免了传统的插值方法用统一的模型逼近所有像素的不足,它对不同的情况采用不同的插值方法。理论分析和实验结果表明了该方法的有效性。

关键词: 图像插值,双线性插值,平面插值,球面插值,图像旋转

Abstract: Rotation algorithm for image interpolation methods has some shortcoming．It often can make the image blur or have saw-tooth shaped edges phenomenon．This paper changed the model of expressing image．A image interpolation method combining plane interpolation and spherical interpolation was proposed．It avoids the traditional interpolation uses unified model to approximate all pixels．In different circumstances it will use different interpolation methods．Finally,the theoretical analysis and experimental results show the effectiveness of the method.

Key words: Image interpolation,Bilinear interpolation,Plane interpolation,Spherical interpolation,Image rotation
