摘要：In several applications, the trajectory of an entity, a feature or an object has to be tracked over asequence of image frames. When the processing is to be performed in real time, there are importantconstraints leading to the parallelization of tracking algorithms.This paper presents the results of a concrete implementation, which deals with the particular case ofsimple objects moving in an context reachable by the vision element (video camera). The steps involvedin the solution development are detailed, specially in relation to their parallelization by using acomputer heterogeneous network and MPI (Message Passing Interface) support.Finally, an analysis of the different algorithms behavior is carried out together with the obtained resultsassessment, which allows knowing the performed parallelization efficiency, and determining underwhich conditions this solution turns out to be the best one
