Abstract
A method and apparatus are provided for classifying image data. A neighborhood average gray value may be determined for the input image data. A threshold value may then be determined based on the neighborhood average gray value. Pixels are evaluated to determine if a gray level difference between the pixel and the neighborhood average gray level is greater than the threshold.
