摘要
本文在分析CT图片的特点的基础上 ,采用经典的Roberts算子对其进行边缘检测 ,并对其进行了阈值分割、细化、最后采用轮廓跟踪的方法 ,在VC6.
The paper mainly introduces a way of contour extraction. First Roberts operator is used to edge detection, then a threshold is used to divide the pixel value into two parts that predigest the calculation, finally contour is selected by a trace arithmetic. This method has been realized on VC 6.0 and abstracted successfully the different contours of CT images.
