title: How can i identify the type of noise present in the images
body: <p>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.</p>
