【摘要】 本文提出了一种新的灰度直方图的阈值点自动提取方法。利用灰度直方图的直观特征,把直方图的峰点作为分水岭,每两个相邻的峰值点和两者之间的谷点组成一个水域。从最低的谷点向上升高水位,直到各个水域水满为止。找到水量最大的几个水域,其谷底就是作为分割阈值的谷点。更多还原

【Abstract】 In this paper,we propose a novel auto-detection algorithm of thresholds and peaks in image histogram.In accordance with the intuitionistic features of the histogram,the peaks of the histogram are considered as watersheds,each valley including two neighboring peaks and a bottom point.We raise the water level up from the bottom point until every valley is full of water.At last,we obtain several valleys with the largest amount of water,and the bottom of these valleys becomes a segmentation threshold.更多还原
