This is a library for trajectory outlier detection based on code provided publicly by Jae-Gil Lee at http://dm.kaist.ac.kr/jaegil/.
The algorithm that this code executes is from a paper entitled "Trajectory Outlier Detection: A Partition-and-Detect framework", and can be found here.
Sample code using the library is provided in main.cpp and can be compiled with the command "make". A C++11 compatible compiler and gnuplot are required.
For more details see the project page.
