Gaussian filtering in one, two or three dimensions is among the most commonly needed tasks in signal and image processing. Finite impulse response filters in the time domain with Gaussian masks are easy to implement in either floating or fixe

用非分离重复过采样正交变换对图像进行去模糊，去噪声，超解像实验。-Repeat with the non separation of the image to blur, noise sampling orthogonal transform, super resolution experiment.
