Abstract
This paper gives a method for distinguishing the states of the two dimensional LMS algorithm as it enhances an image in an area having high contrast variations or in an area having low contrast variations. This capability is used to automatically adjust the algorithm step size to improve image enhancement as the degree of contrast variation changes over an entire image
