Syntax

 #include <xite/snn.h>

 int snn( IBAND input, IBAND output, int dx,
    int dy );

Description

snn performs symmetric nearest neighbour noise reduction and edge sharpening. Uses rectangular processing window of size dx * dy.

Restrictions

input and output must have pixel type unsigned byte or unsigned short. The types must be identical. Even values of dx and dy are increased by one.

Return value

 0 => ok
 1 => Bands have different pixel types
 2 => Bad pixel types
 3 => Bad dx value
 4 => Bad dy value
