| 文章提出了一种利用Bézier插值曲面进行图像放大的方法,该方法是为数字图像的每一个色彩分量构造一个分块双三次Bzier插值C1曲面,图像放大等价于以不同的采样速率对该曲面进行采样的过程.实验结果表明,该方法可以大大改善放大图像的效果. |

| Abstract: |
| A method of image zooming-in is presented in this paper. It is based on Bézier interpolation surface. First, it constructs a piecewise bicubic Bézier interpolation C1 surface for each color component of a digital image, and then, samples the surface with different sampling rate to zoom in. The experimental results show that the method can improve the quality of zoomed image greatly. |
| Key words: Zoom in, Bézier surface, interpolation, acceleration, pixel decompose. |
