The purpose of this research is to propose and test a method for detecting intersections by analysing collectively acquired trajectories of moving vehicles. Instead of solely relying on the geometric ...
On Typability for Rank-2 Intersection Types with Polymorphic Recursion
Typability Rank-2 Intersection Types Polymorphic Recursion
2016/5/24
We show that typability for a natural form of polymorphic recursive typing for rank-2 intersection types is undecidable. Our proof involves characterizing typability as a context free language (CFL) g...

Describing topological relations Voronoi-based 9-intersection model
2016/5/20
The Voronoi-based 9-intersection model (V9I) is a modified version of the original point-set-based 9-intersection model.The modification is made by replacing the complement (exterior) of an entity wit...
改进后Ray-Box Intersection权系数矩阵的SART+TVM重建算法
联合代数重建 全变差最小化 Ray-BoxIntersection算法 双线性插值算法 权系数矩阵
2016/7/28
针对均匀采样稀疏型重建问题，研究了Ray-Box Intersection和传统的双线性插值两种权系数矩阵计算方法。对Ray-Box Intersection算法的逻辑漏洞进行了改进，利用直线生成法并结合射线斜率和像素位置关系提出了改进算法。该算法利用代数关系求得射线穿过重建区域的起点和终点，然后取不大于其坐标的最大整数，最后采用直线生成法，依据射线斜率沿X或Y方向得到该条射线在投影区域内经过的所...
