Name
morphErode - morphological grayscale erode on a band.
Syntax
#include <xite/morph.h>
int morphErode( IBAND inband, IBAND outband,
ISS_BAND B );
Description
morphErode calculates the morphological operation
erode, on the band inband, with a structuring
element B. The result is sent to the band specified
in outband. The actual calculation is performed with the
equation:
outband(x,y) = min[inband(x+i,y+j)-B(-i,-j)]
with i and j inside the structuring element B
and (0,0) as the center pixel of B.
Restrictions
inband and outband must have pixel type unsigned byte.
B must have pixel type signed short.

Return value
0 : OK
1 : Bad input pixel type
2 : Bad output pixel type
3 : Bad pixel type for structuring element
