摘要：

Most thresholding algorithms have difficulties processing images with unimodal distributions. In this paper an algorithm, based on Ending a corner in the histogram plot, is proposed that is capable of performing bilevel thresholding of such images. Its effectiveness is demonstrated on synthetic data as well as a variety of real data, showing its successful application to edges, corners, difference images, optic flow, texture difference images, polygonal approximation of curves, and image segmentation.
