morphDilate
[ XITE Reference Manual | XITE home ]
Name
morphDilate - morphological grayscale dilate on a band.
Syntax
#include <xite/morph.h>
int morphDilate( IBAND inband, IBAND outband,
ISS_BAND B );
Description
morphDilate calculates the morphological operation
dilate, on the band inband, with a structuring
element B. The result is sent to the band spesified
in outband. The actual calculation is performed with the
equation:
outband(x,y) = max[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
B must have pixel type signed short, inband and outband
must have pixel type unsigned byte.

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