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。
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.
