fwind2
2-D FIR filter using 2-D window method
Description
The fwind2
function designs 2-D FIR filters using the
window method. fwind2
uses a 2-D window specification to design a
2-D FIR filter based on the desired frequency response. fwind2
works
with 2-D windows only. Use fwind1
to create a 2-D FIR filter from a
1-D window.
You can apply the 2-D FIR filter to images by using the filter2
function.

fwind2
computes h
using an inverse Fourier
transform and multiplication by the two-dimensional window
