摘要:

本文运用局部多项式的方法对图像进行插值。文中我们从一幅高分辨率图像通过下采样得到一张低分辨率图像,然后对其进行插值并求出插值图像的峰值信噪比(PSNR)。为说明本文方法的可行性,我们把本文的方法与传统的插值方法进行了比较。实验表明本文所运用的方法比传统插值方法具有更高的PSNR,故本文的方法对图像插值是有效可行的。

In this paper, we use method of local polynomial to deal with image. Firstly, we obtain low resolution images by down-sampling from the high-resolution images, and then interpolate the obtained low- resolution images and calculate the peak signal to noise ratio. To illustrate the feasibility of this method we compare it with the traditional interpolation method. Experiments show that the method applied in this paper has higher PSNR than traditional interpolation, thus this method of image interpolation is feasible and effective.
