Finally, a complete light knife center contour is obtained through refinement and repair for data. 最后,对光带数据进行细化、修补,获得完整的光刀中心轮廓线。
It uses the maximum and minimum images by threshold segmentation to detect the light. A contour tracking algorithm is used to locate light, and further identify light. 利用图像序列的最大值和最小值图像通过阈值分割的方法进行光源的检测;利用轮廓跟踪算法和消除弱小点进行光源的定位,并进一步识别出光源的编号。
CV models just shed the light on single object contour extraction. The major cause is it makes the level-set-function driven contours to split in some targeted areas, which do not make use of topology split information of the contours effectively. CV模型只能实现单目标的轮廓提取,主要原因是不能使水平集函数驱动的轮廓线在某些目标区域正确分裂,没有有效利用轮廓线的拓扑分裂信息。
In this paper, a new lensless digital holography system with short-coherent light source is designed for recording three-dimensional surface contour of reflecting micro-object. 针对反射型微小物体,设计了一种可在三维形貌测量中实现微小物体分层记录的短相干光源无透镜傅里叶变换数字全息记录系统,并利用该系统对锥形微孔壁实现了分层记录。
Nocturnal insects, which are usually active in dim light but not in complete darkness, react to contour. 夜出性昆虫常常活动于微暗但不是完全黑暗中,对形状有反应。
