[OctDev] Greylevel morphological operations

[Etienne G. <et...@cs...>]

  Hi All,

I consider adding some greylevel image morphology functionality to
octave-forge. I have this function:


## im2 = g_all (im,scales)       - Greylevel morphological opertations
##
##      Open, close, erode and dilate greylevel image im at various scales.
##      Dilation at scale s is the greatest greylevel within radius s.
##      Erosion  at scale s is the least greylevel within radius s.
##      Opening  is erosion followed by dilation (all at the same scale).
##      Closing  is dilation followed by erosion (all at the same scale).
## 
## im     : R x C       : Image
## scales : 1 x S       : Scales at which morphological operations are performed
##
## im2     : R x C x 4*S : Opened (4*i+1), closed (4*i+2), eroded (4*i+3) and
##                        dilated (4*i+4) images (i in 0:S-1)
##
## See also: g_open_close.
## Todo    : Make this function more efficient.

  Any suggestions on other possible interfaces? I can also put
fucs for individual operation.

   Cheers,

  Etienne
