| 摘 要： | 检测泡罩包装中的药片是否存在形状缺陷,需要提取药片图像边缘轮廓。"爬虫"法是基本的边缘跟踪方法。提出一种基于有记忆的变窗"爬虫"轮廓跟踪的缺陷判别方法,利用封闭轮廓曲线的密集度指标,"爬虫"跟踪的陷阱和边缘分支,设置"爬虫"中止变换的窗口大小,可快速实现缺陷的预判,从而有效地提高后续缺陷识别过程的工作效率。

| Abstract: | Boundary contour of the tablet image should be extracted when the shape defect is detected for the rotundity tablets in blister packaging.The reptile is a basic method for boundary contour tracking.A method has been presented to distinguish tablet defect based on the reptile with memory and alterable window for image boundary tracking.Some parameters have been used to distinguish tablet defect beforehand,such as the pixel density of closed contour curvet,he trap and embranchment tracked by reptile and the alterable window size to stop tracking.So the efficiency would be improved effectively for the defect recognition in the behind image processing. |
