| 摘 要： | 根据开发数字化适形铅模系统的需要,研究了由X光片中提取出靶区轮廓的方法。对于标有靶区轮廓的X光片扫描图像,首先进行窗口变换,然后进行阈值变换使其二值化,接着对图像进行增强处理,最后进行细化,最终提取靶区轮廓坐标数据。

| Abstract: | Depending on demand of dereloping digitized lead-mould system,a method to extract the target contour from the X-ray pictures is studied.The contour extracting approach is based on imageprocessing technologies,by getting the fihal contour coordinate dara through the operations of Window transform,binary dara transform,image enhancement,contour thinning and etc. |
