图像阈值分割算法实用技术研究与比较

Study on applied technology arithmetic of image threshold segmentation

在众多的图像分割技术中,阈值化技术是基于区域的图像分割技术,是图像分割中最重要而有效的技术之一。本文给出了几种常用图像阈值分割方法的原理和性能评价比较,并将一种应用最广泛的Otsu法的改进方法运用于机车入库系统中检测受电弓与滑板的磨耗情况,使维护人员无需上车检查;大大减轻了检修人员的劳动强度。

Threshold technology which is one of the most important and efficiency technology in image segmentation is based on area image segmentation in many arithmetic. Principle and performance of several image segmentation arithmetic in common use has been involved in the thesis. And the improved Otsu arithmetic has been used for detecting abrasion of locomotive pantograph and catenary in warehouse entry system. So their labor intensity has decreased greatly.
