手动获取坐标，snake轮廓检测。所要分割目标的轮廓确定大致的初始轮廓曲线(手动点 出),然后对曲线进行能量最小化变形。-Manually get coordinates, snake contour detection. To split the contours of the target to determine the approximate initial contour curve (manual points out), then the curve deformation ene

DRLSE对脑肿瘤分割：提供一张真实的脑部肿瘤MRI图像做测试，可以手动勾画出是轮廓，初始轮廓勾画的越精准，迭代次数要求越低，效果越好(DRLSE segmentation of brain tumors)
