Write a program that accepts as input an image and prompts the user for the
coordinates of a sub-region of the image which is suppose to represent a near-constant
grey-level region. Then using this region, estimate the mean and standard deviation
of the Noise using the formulas previously described here. Print out the values to the user.
Try running the program with a few images with a
variety of noise added to them to test the results. Here are some examples you
can use:
| Image 1 (tif) Image 2 (tif) |
