[ XITE Reference Manual | XITE home ]
Name
thresMlReddi - multi-level thresholding by Reddi et al.
Syntax
thresMlReddi [-nt <no_of_thresholds>] [-eq] [-s <scale>]
<inimage> [<outimage>]
Description
thresMlReddi performs multi-level thresholding
according to the method of Reddi et al. (see ref).
By default, the different areas are labeled from 0 up
to no_of_thresholds. If outimage is supplied, thresholding
is performed. Otherwise the threshold values are written
to stdout.
Options
-
-nt no_of_thresholds
- Desired number of thresholds.
-
-eq
- Spread output values equidistantly.
-
-s scale
- Spread output values with scale.
The -eq and -s options only have meaning
if outimage is given.
