Developpments

Following are some possible developpments for future versions of BlueNile.

  1. Enable filtering of each layer of RGB images.
  2. Offer more shapes for filtering, such as rings, quarters...
  3. Make smooth passage from filtered to unfiltered regions (Butterworth filtering).
  4. Non-equal sided regions in autodetection mode.
  5. Autoselect wide spreads.
  6. Give the mesures for frequencies, slant and spread.
  7. Apply other methods for localizing maximas (cf. D.G. Bailey, Detecting regular patterns using frequency domain self-filtering, 1997 Intl. Conf. on Img. Proc. vol. 1 p. 440).
  8. Load masks.
  9. Handle selections spreading over the border.
