NoiseUniformInit,
NoiseUniformInitFp
Initializes parameters
for generating noise
signal with uniform
distribution.
void iplNoiseUniformInit ( IplINoiseParam* noiseParam ,
unsigned int
seed , int low , int high );
void iplNoiseUniformInitFp ( IplINoiseParam* noiseParam ,
unsigned int
seed , float low , float high );
noiseParam Pointer to the structure that contains parameters
for the noise generator.
seed The initial seed value for the pseudo-random
number generator.
low, high The lower and upper bounds for the range of
uniformly distributed values.
Discussion
Use functions iplNoiseUniformInit(), iplNoiseUniformInitFp() to
initialize the noiseParam structure if you want to generate the noise signal
with uniform distribution over the range [
low , high ]. After that you can
call the
iplNoiseImage() function, which actually generates and adds
the noise signal.
