| 摘 要： | 提出了一种基于Thiele-Thiele型有理向量插值的彩色图像插值方法。将数字图像的每一个像素点看成是一个平面域的关于RGB三原色的一个向量,在矩形网格上利用Samelson逆与倒差商技巧,根据图像的像素特征构造Thiele-Thiele型二元向量连分式有理插值函数,然后对插值曲面进行采样以实现缩放。采用该算法可以得到更加清晰的放大图像。实验结果表明,该方法是一种有效的图像缩放方法。

| Abstract: | This paper presented a new method of color image zooming which based on the bivariate Thiele-Thiele's vector va-lued rational interpolation.Regarded each pixel of digital image as a vector of RGB primary colors of a flat field,Samelson inversion and inverted difference quotient was used to construct bivariate Thiele-Thiele's vector valued rational interpolation function according to the pixel features of the image,resampled the interpolation surface to generate the required resized image.The more distinct i... |
