Developpments
Following are some possible developpments for future versions of BlueNile.
- Enable filtering of each layer of RGB images.
- Offer more shapes for filtering, such as rings, quarters...
- Make smooth passage from filtered to unfiltered regions (Butterworth filtering).
- Non-equal sided regions in autodetection mode.
- Autoselect wide spreads.
- Give the mesures for frequencies, slant and spread.
- 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).
- Load masks.
- Handle selections spreading over the border.
