Syntax
#include <xite/extrema.h>
int extrema2( IBAND inband, IBAND outband,
int min, int max, int bg );
Description
Local extrema (minima and maxima) are detected in

marked with value min, maxima are marked max,
and all other pixels are marked bg, background.
If you do not want to distinguish between minima
and maxima, see extrema1.
Restrictions
Supports only unsigned byte.

Return value
0 => ok
1 => bad input pixel type
2 => bad output pixel type
3 => bad min, max or bg value
