A simple modification of MATLAB's "graythresh" to use 65536 levels for 16 bit images, rather than 256.
MATLAB's "graythresh" uses a histogram of 256 bins regardless of input image class. This can lead to poor choices for threshold values for, for example, 16-bit images that use a small fraction of the full range. Also, it's odd to avoid using the full bit depth. Therefore, this version uses 65536 bins for 16-bit images (uint16 or int16), and 256 for 8-bit, single, or double.
