[1] Trajectory Similarity Algebra

\tableofcontents

\noindent

1 Introduction

The Trajectory Similarity Algebra provides operators to measure the distance
or similarity of trajectories.

These similarity measures work on sequences of points or on sequences of tuples
of instants and points. Therefore this algebra provides the type constructors
~pointseq~ and ~tpointseq~. See the file {\tt PointSeq.cpp} for more
information.

The distance and similarity operators are implemented and described in detail in
the following files:

  * {\tt EndPointDistance.cpp}

    * ~dist\_origin~

    * ~dist\_destination~

    * ~dist\_origin\_and\_destination~

  * {\tt EuclideanDistance.cpp}

    * ~dist\_euclidean~

  * {\tt LCSS.cpp}

    * ~lcss~

    * ~rel\_lcss~

    * ~dist\_lcss~

  * {\tt LIPDistance.cpp}

    * ~dist\_lip~

    * ~dist\_stlip~

    * ~dist\_spstlip2~

    * ~genlip~

    * ~genlip2~

The classes, structs, and functions of this algebra reside in the C++ namespace
{\tt tsa} (short for Trajectory Similarity Algebra).

This file implements the class ~TrajectorySimilarityAlgebra~ that registers the
algebra's type constructors and operators with SECONDO. The type constructors
and operators themselves are implemented in separate files of this algebra.
