%X Choosing a good Interpolating template is the key to better recover the subsampled image with low distortion.The All Phase Digital Filter is a new type of linear phase filter.According to All Phase theory,we propose 2-D Walsh interpolating template.Here a new method is applied: first diagonal interpolation,second horizontal interpolation and vertical interpolation.This algorithm has been compared with the nearest interpolation,bilinear interpolation,spline interpolation.Simulation results show this algorithm is with less computation complexity and can reduce the influences from noise.
