A Spatial-Contextual Indoor Trajectory Prediction Approach via Hidden Markov Models

Algorithm 4

Trajectory prediction.

input: A set of indoor trajectory sequences

output: The predicted trajectory point at timestamp.

1: Initialize parameters;

2: if T.length 0 then

3:  Return FALSE;

4: end if

5: RT =Viterbi(T);

6: for i =0 to m_DimA do

7:  Compute ProNext

8:  Rank

9: end for

10: Return
