| 摘 要： | 针对现有的图像插值方法存在的不足,在图像放大中容易出现"锯齿"形边缘和模糊的现象,改变了图像的表示模型,提出了平面插值、球面插值、斜平面插值、双三次插值相结合的图像插值方法,避免了传统的插值方法用同一个模型逼近所有像素存在的不足.理论分析和实验结果表明了文中所提方法的有效性.

| Abstract: | The existing image interpolation methods have some shortcomings,i.e.,the image blur or saw-tooth shaped edges in enlarged image.In the paper,the image representation model has been modified,and the image interpolation methods are given for the plane interpolation,spherical interpolation,slope interpolation and bicubic interpolation in order to avoid the shortcomings of the traditional interpolation methods in which all the pixels are approached with the same model.Through the theoretical analysis and experimental results,the given methods of image interpolation are shown effectiveness. |
