Threshold segmentation method based on expected characteristic of image queue
基于图像序列期望特征的阈值分割方法*

In order to overcome the high complexity and poor efficiency of the conventional self-adaption threshold segmentation mothod, this paper proposed a fast segmentaiton method based on the expected characteristic of image queue. The principle and process of the method was explained by taking the expected area of image background as an example. Comparing with the Ostu algorithm, it discussed the practicabilty and efficiency of the method. Demonstrated by the application of segmentation of screw bolt image of carriage, the validity of the method was acknowledged.
