I'm looking for an example on how to use the labview GPU toolkit to compute the FFT of an 8bit grey-scale image.
In the attachment you will see that the FFT is not happy with its input.
Can somebody provide a simple example on how to do this?
Have you tried changing the drop down on the FFT VI to something other than SGL. It looks like you might be iniitalising it as a U8?
If not might be worth posting this on the GPU Community : https://decibel.ni.com/content/groups/gpu-computing but here are some resources to get you started.
