Data

Goal

For a given image:

  • Perform a spectral analysis
  • Resize the image to get a smaller image of half size
    • in the space domain by subsampling
    • by resizing in the Fourier domain
  • Resize the image to get a bigger image of double size
    • by sinc interpolation (zero padding in the Fourier domain)
    • by linear interpolation in the space domain
