snake
- 在数字图像中虹膜位置的有效定位是虹膜识别的关键问题。用一种基于主动轮廓线模型的方法定位虹膜的位置,先用灰度投影法检测出瞳孔内的一点作为瞳孔的伪圆心,该圆心只要能落在瞳孔内部即可。然后以该伪圆心为中心,在其周围等角度间隔地取N个点作为初始的snake基准点,按照snake 的运行机制不断进化,直到虹膜的内边界为止。最后,计算进化后的snake形心和snake上的控制点与该形心的距离,取其平均值作为瞳孔的半径,动态轮廓模型的形心作为瞳孔的圆心,即可准确定位出虹膜内边界的位置。实验表明,与常见的定位方

- 在大地测量学中,坐标系分为两大类:地心坐标系和参心坐标系。地心坐标系是坐标系原点与地球质心重合的坐标系,参心坐标系是坐标系原点位于参考椭球体中心,但不与地球质心重合的坐标系。我国使用的1954北京坐标系,1980西安坐标系都属于参心坐标系。GPS中使用的世界大地坐标系WGS-84属于地心坐标系,我国最近开始启用的中国大地坐标系2000(即CGCS2000),也属于地心坐标系。以上两大类坐标系都有下列几种表达形式:1.空间大地坐标系,即大地经纬度(B,L,H)形式2.空间直角坐标系,即三维空间坐标
