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
