title: Authors' reply.
abstract: The comment of Stig Steenstrup on the use of gray level entropy function in our paper' has been addressed. The entropy measure has not been used in the procedure of enhancement, but it has only been used to show statistically that the enhanced images have larger gray level entropy, and therefore better utilize the gray levels.
