gifseg(2) Scilab Function gifseg(2)
NAME
gifseg - Replaces nodes of the diadic tree by a ceratin unique value.
Author: Khalid Daoudi
Replaces at each scale the left (resp. right) nodes of the diadic tree,
associated to the GIFS coefficients, that belong to [cmin,cmax] by a cera-
tin unique value.
Usage
[Ci_new, marks, L]=gifseg(Ci,[cmin,cmax,epsilon])
Input parameters
o Ci : Real matrix Contains the GIFS coefficients (obtained using FWT)
o cmin : Real scalar [1,n] Specifies the minimal value of the Ci's to
be considered (cmin=0 by default)
o cmax : Real scalar [1,n] Specifies the maximal value of the Ci's to
be considered (cmin=0 by default)
o epsilon : real scalar Specifies the maximal error desied on the
Ci's approximation.
Output parameters
o Ci_new : Real matrix Contains the the new GIFS coefficients.
o marks : Real vector Contains the segmentation marques.
length(marks)-1 is the number of segmented parts.
o L : Real matrix A structure containing the left and right lambda_i's
corresponding to each segmented part.
