Is there a way to perform cufft(R2C & C2R) for a specific region of interest in a bigger array using offsets?
For example,Consider a image of 1920x1080 size. I would like to perform FFT for ROI of 720x960 in that image. Is there a way to perform FFT directly on the ROI data, Without copying the ROI data into separate array ?
I have tried using cufftPlanMany but i got incorrect results.
Thanks in Advance.
