We discussed then how to compute two-dimensional digitalconvolution and two-dimensional DFT with the polynomial transforms, which are introduced in this paper.
然后讨论用这种多项式变换计算二维数字卷积和二维dft的方法。

With this technique, the digital image convolution can be realized, therefore, the image low-pass filtering, image high-pass filtering, edge-enhancing could be realized.
采用这种技术，可以实现数字图像卷积运算，因此可以完成图像的低通滤波、高通滤波、强化边缘等处理。

In this paper, a new method is proposed to solve the problem by investigating convolution reconstruction of digital holograms.
