Adjust Image Contrast Using Histogram Equalization

I have a greyscale image which has pixel values ranging from 1.000 to 1.003. I would like to increase the contrast between the different pixels.

Histogram equalization seeks to flatten the image histogram so that the intensities are more or less equiprobable in being encountered in the image.
