Rayleigh Noise With PDF In Digital Image Processing (CSE)

by


Rayleigh noise
The PDF of Rayleigh noise is given by  
(1)
The mean and variance of this density are given by
                                                                               
                                      ……(2)
and                                        
                                   ……(3)

 Rayleigh Noise is generated due to Range imaging
Fig. Rayleigh Noise PDF

fig. shows a plot of the Rayleigh density. Note the displacement from the origin and the fact that the shape of this density is skewed to the right. The Rayleigh density can be quite useful for approximating skewed histograms.
