提出了一种确定投影方向的方法。同时使用任意数量的未知三维结构的投影作为输入。该方法以公共线为基础，采用一种新的差异度量，考虑了公共线在角空间上的不均匀分布。应用70 S大肠杆菌核糖体的数据从能量过滤电子显微镜得到的描述。
A method is proposed for determining the directions of projections. An arbitrary number of projections of unknown three-dimensional structure are simultaneously used as input. The method is based on common lines and uses a new discrepancy measure accounting for the uneven distribution of common lines ir. angular space. An application to the 70S Escherichia coli ribosome data obtained from an energy-filtering electron microscope is described.
