Threshold Selection Techniques, 3.

Abstract

This report describes the implementation of a standard technique for selecting a picture segmentation threshold by examining the gray level histogram of the picture. The histogram is least-squares approximated by a sum of two or more Gaussians, and the maximum-likelihood threshold between these is determined. Results are shown for several different types of pictures, including handwriting, chromosomes, and cloud cover.
