Thread Subject: Poisson Noise Generation

Hello,

I need to generate poisson noise in MATLAB. For image processing we can use the following

For any image I

J= imnoise(I, 'poisson').

This add poisson noise to the image. My question is, Can I use the same concept to add poisson noise to a given signal.

For any given signal S

J= imnoise(S, 'poisson')

Is it valid? Does this mean that I am adding noise based on poisson distribution to the signal.

Please let me know.

Thanks,
Rajeev
