GaussianNoise

Generate an image disturbed by Gaussian noise

SYNOPSIS

#include "dip_noise.h"

dip_Error dip_GaussianNoise ( in, out, variance, random )

DATA TYPES

integer, float

FUNCTION

Generate an image disturbed by additive Gaussian noise. See GaussianRandomVariable for more information on the random number generator.

ARGUMENTS

Data typeNameDescription
dip_ImageinInput
dip_ImageoutOutput
dip_floatvarianceVariance of the Gaussian distribution the noise is drawn from
dip_Random *randomPointer to a random value structure

EXAMPLE

Get a image with additive Gaussian noise as follows: 

   dip_Image in, out;
   dip_float variance;
   dip_Random random;

   variance = 1.0;
   DIPXJ( dip_RandomSeed( &random, 0 ));
   DIPXJ( dip_GaussianNoise( in, out, variance, &random ));
