maxHisto
[ XITE Reference Manual | XITE home ]
Name
maxHisto - texture measure
Syntax
#include <xite/median.h>
int maxHisto( IBAND input, IBAND output,
int nx, int ny );
Description
Filters the input band into the output band
using a local filter with window size nx x ny.
The number of occurrences of the pixel value
occurring most frequently in the window becomes
the new center value. Even values of nx or ny
are increased by one. Uses histogram updating
when moving horizontally from pixel to pixel.
If histogram value is larger than 255, 255 is used.
Return value
0 => ok
1 => bad pixel type input band
2 => bad pixel type output band
3 => bad nx value (less than 1 or greater than xsize)
4 => bad ny value (less than 1 or greater than ysize)
