I intend to add, artificially a gaussian noise to a digitized image.
The process I presently have in mind is the following one:
1- calculation of the mean value of the image intensity
2- generate a random number, with a gaussian distribution
(mean value = 0.0, standard deviation = percentage of the
mean value)
3- add the random number to the value of each pixel of the
initial image.
What do you think of that method? Any suggestion and remark are welcome!
I will send a summary of eventual responses, upon request.
please e-mail responses to following address.
thanks,
