Image FFT

[LabView/LabWindows/CVI]

Dear Friends,
I am working on a BMP File ...i want to apply FFT on this IMage file which is a BMP extension .Since matlab does i want to know how in Labview 6.1

Hi,

If I recall correctly a 2D FFT can be acheived by applying a 1D FFT first
for every horizontal line, and then for every vertical line of the resulting
image. For the 1D FFT you can use the FFT function in LabVIEW, although it
might not be part of every LabVIEW version.

Regards,

Wiebe.

Hello Rajeev,

This can be accomplished easily if you have the imaq vision software for LabVIEW. There is an imaqFFT function which you just input the image data type and it performs the FFT on the image. Otherwise you can use the regular labview functions and perform the FFT for both dimensions. Have a good one.
