| 1. | Among them , the improved initiative profile mode draw - out algorithm not only can precisely drawing out in the image the convexity object edge ; but also can approach the hollow place of the edge 。 at the same time , it introduced the auto - adapted changing size exterior restraint energy to increase the attraction scope , enables the control point not to 其中,改进主动轮廓模型的边缘提取算法不但能精确地提取图像中的凸形物体的边缘,而且能够接近边缘的凹陷处;同时,它引入了自适应改变大小的外部约束能量来增大吸引范围,使控制点能够不依赖于初始轮廓而快速地收敛到目标的真实轮廓。 |
