For a conventional digital signal processing in the signal agriculture often contain clutter noise pollution first performs a Fourier transformation,and then after filtering apparatus operation group,then its inverse Fourier transform more'purely' signal,but the filtering operation process;because of the low-pass filter smoothing effect,and instantly eliminate high-frequency noise will make the edge information and the texture characteristic mutation or redundant,to a certain extent this will have a negative impact on the image filtering process,thereby affecting the image data processing this...
