【摘要】 边界跟踪方法是图像识别和图像测量过程中的重要预处理手段,但是传统的“爬虫”边界跟踪方法存在着准确性与速度上的矛盾。综合小窗口“爬虫”的快速性和大窗口“爬虫”的准确性提出了一种有记忆的变窗“爬虫”边界跟踪方法。这种“爬虫”在跟踪边界的过程中根据需要灵活变换窗口大小,并按“像素中心点到直线距离最近”规则填充断点。这种方法有效的解决了跟踪速度和跟踪准确性的矛盾,由于其具有记忆能力,所以对于陷阱和边缘分支问题也可以妥善解决。实验结果表明,该方法具有较理想的效果。更多还原

【Abstract】 Boundary tracing method is an important preprocessing instrument for image recognition and image measurement. But the traditional reptile boundary tracing method exits a conflict between veracity and speed. It integrates the speediness of small window reptile and the veracity of big window reptile, and presents a new reptile method with memory and alterable window for image boundary tracing. The window of the reptile is neatly altered according to the tracing requirement, and it fills the breakpoint in the rule of minimum distance from pixels center to beeline. The method effectively solves the conflict between veracity and speed, and has well done with the problems such as trap and embranchment. The experiments for this method indicate that it has satisfying resuits.更多还原
