自适应参数的轨迹压缩算法
Trajectory compression algorithm with adaptive parameter
摘要
Abstract
In order to overcome the disadvantage that it was hard to confirm the perfect compression threshold while the algorithm running,this paper presented trajectory compression algorithms with adaptive parameters.This method,based on the compression effort that users expected and the strategy ensuring the compression ratio priority,could help users to automatically determine the compression threshold while guaranteeing the compression efficiency and effect.It would avoid users found the perfect compression threshold by their experience and repeated experiments.The experimental results show:adaptive parameters combined with the non-iterative compression algorithms guarantee the compression efficiency of original compression algorithms and solve the problem that it is hard to confirm the perfect compression threshold,at the same time also improve the compression effect of the original compression algorithms;adaptive parameters combined with the iterative compression algorithms reduce the compression efficiency of original compression algorithms,but solve the problem that it is hard to confirm the perfect compression threshold,at the same time also improve the compression effect of the original compression algorithms.关键词
