函数paddedsize可计算P和Q的最小偶数值,PQ则是避免折叠误差的串扰所采用的补零方法。
函数dftfilt是用于频率域滤波的M函数
在house中进行空域滤波与频域滤波的比较
函数dftuv创建用于实现频率域滤波器的网格数组
在number中进行低通滤波
还可基于lpfilter生成高通滤波器。
函数D=hypot(U,V)<=>D=sqrt(U.^2+V.^2)替代
函数f=tofloat(f)<=>f=im2double(f)替代-Paddedsize calculate P and Q function minimum even value, PQ is zero-padded to avoid aliasing errors Crosstalk being used.
Dftfilt function is used for frequency domain filtering function M
Comparing spatial filtering and frequency domain filtering in the house in
Function dftuv create a grid array is used to implement frequency domain filter
Low-pass filtering in number of
It can also generate a high-pass filter based on lpfilter.
Function D = hypot (U, V) <=> D = sqrt (U. ^ 2+ V. ^ 2) substitute
Function f = tofloat (f) <=> f = im2double (f) Alternate
