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
