You can use this script for Local Adaptive Thresholding.

Or if you want bones as white color you should use sobel-operator, as in this example.

A simple way,you can just change the value of a pixel, when it is higher than 125 change it to 255,or set 0. the number 125,you can change it,to get a best one. you can search "binarization" on google to get more information.
