Abstract
V delu predstavimo analizo delovanja kratkoročnih in dolgoročnih sledilnikov na videoposnetkih, narejenih v vodnem okolju. Iz obstoječih podatkovnih baz, posnetih na morski površini z majhnega plovila, ustvarimo dve novi podatkovni bazi. Prva je primerna za testiranje kratkoročnih sledilnikov, druga pa za testiranje dolgoročnih sledilnikov. Na podatkovnih bazah nato testiramo nekaj kratkoročnih in dolgoročnih sledilnikov, ki so dosegli najboljše rezultate na tekmovanjih Visual Object Tracking. Rezultati kratkoročnega sledenja so predstavljeni v obliki pričakovanega povprečnega prekrivanja, povprečnega prekrivanja, števila odpovedi in krivulj pričakovanega povprečnega prekrivanja. Analiziramo tudi hitrost procesiranja sličic kratkoročnih sledilnikov. Poleg nadzorovanega eksperimenta na njih opravimo še realnočasovni eksperiment. Pri dolgoročnih sledilnikih rezultate predstavimo z grafi primerjave natančnosti in priklica ter grafom F-ocene. Tudi dolgoročnim sledilnikom testiramo hitrost procesiranja sličic. Rezultati so analizirani in primerjani z rezultati v podobnih študijah.

Title:Comparison of Short-Term and Long-Term Trackers in the Waterborne Environment
Abstract:
In this work, an analysis of short-term and long-term trackers performance on marine-based dataset of video sequences is presented. To this end we used already existing marine datasets to create two new marine datasets. The first dataset is suitable for short-term tracking analysis, while the other one is suitable for long-term tracking analysis. We perform experiments on those datasets using some of the top-performing short-term and long-term trackers based on their Visual Object Tracking competitions performance. The results of short-term tracking are presented in form of expected average overlap, average overlap, number of failures and expected average overlap curves. Processing speed of short-term trackers is also evaluated. In addition to the supervised experiment, realtime experiment is performed as well. The results for long-term trackers are presented as a precision-recall graph and F-score graph. Long-term trackers are evaluated based on their processing speed as well. The results are analyzed and compared to results in similar studies.

Keywords:computer vision, short-term tracking, long-term tracking
