FFT Cuda

Input

• Image is presented in TIFF file structure
• Array of, FFT of kernels (64x64)

Todo

• Take a windows 128x128, step by 32 pixels
• Make a FFT (DFT_2D)
• Get nth-kernel, pad 32px zero's to each side
• Multiply FFT with kernel
• Inverse FFT of the result
• Save 128x128 window to the n'th position in the TIFF
