How can i identify the type of noise present in the images

I am presently working with noise removal in images. If the only available information in hand is the noise affected gray scale image, how can I identify what type of noise (say, Gaussian, Poisson, speckle, uniform etc.) is present in the image? What may be the parameters that I can consider to identify the type of noise? I am using gray scale images.

One possible way is to analyze histograms of manually selected image fragments that are known to be homogeneous. Which fragments to consider depends of course on the nature of your images.
