Hi Milou,
Morphological profiles operates on single channels images and produce a
profile of morphological operations with increasing structuring element
sizes (hence the initial value, profile step and size). The profile is
stored in a multiband image. Please refer to :
Martino Pesaresi and Jon Alti Benediktsson, Member, IEEE: A new
approach for the morphological segmentation of high resolution
satellite imagery. IEEE Transactions on geoscience and remote
sensing, vol. 39, NO. 2, February 2001, p. 309-320.
For more information.
Regards,
Julien

Hello,
using morphological opening profile on a multispectral image (for
example initial value:2, profile size: 1, step:1 ) what's those
parameter mean?
the result is an image with 4 spectral bands (the real image has 3
spectral bands), why?
Thank you.
