Can any body tell me that how I can find probability distribution function from histogram of any image. i.e. i want to know type of distribution (eg. gaussian, laplacian, etc.) from Histogram of the image.

You can't.

The best you can do is to

1) Postulate a distribution type
2) Compute some key parameters for that type
from the histogram
3) Plot the PDF for these parameters on top
of the histogram
4) Look at the plot and make a subjective
judgement of how well the PDF fits the
histogram
5) Repeat for all PDF types of interest
