Abstract

U radu je obrađeno praćenje više pokretnih objekata temeljeno na metodi praćenja pomoću detekcije. Korištene su Tracktor i Tracktor++ metode, te je radi poboljšanja razvijena Tracktor+++ metoda. Da bi se određeni objekt na snimci uspješno detektirao i pratio korištena je, zbog postignutih rezultata u tom području, konvolucijska neuronska mreža. Inačice Tracktor metode koriste Faster R-CNN, Feature Pyramid Networks, Region Proposal Network i Non-Maximum Suppression algoritam i arhitekture za... More pronalaženje i praćenje objekata. Implementirana su četiri matematička modela za predviđanje trajektorije kretanja objekata kroz sekvence. To su otežani pomični prosjek, alpha - beta filtar, alpha - beta - gamma filtar i Kalmanov filtar. Dodatno je analizirano kako promjena intervala detekcije utječe na performanse različitih inačica Tracktor metoda. Less

Abstract (english)

The subject of this master thesis is multi-object tracking based on tracking-by-detection paradigm. Tracktor and Tracktor++ methods are used and, in order to improve its performance, a Tracktor+++ method is developed. In order for a method to successfully detect and track a certain object, a convolutional neural network is used. All three types of Tracktor methods use Faster R-CNN, Feature Pyramid Networks, Region Proposal Network i Non-Maximum Suppression algorithm and architectures to... More detect and track objects. Four mathematical models are implemented to estimate object's trajectory throughout sequences. These are weighted moving average, alpha - beta filter, alpha - beta - gamma filter and Kalman filter. Additionally, a test is made to check how a change in detection interval affects Tracktor's performance. Less
