Multiple Hypothesis Tracking based on Discriminative Appearance Features of Convolutional Neural Network
2018
Multiple Object Tracking (MOT) has attracted increasing attention due to its academic and commercial potential. However, it still remains challenging due to factors like data association ambiguity and abrupt appearance changes. To address these issues, we extended the multiple hypothesis tracking (MHT) by incorporating the appearance features which extracted from faster region convolutional neural network (Faster-RCNN). Additionally, a principal component analysis method was introduced to update discriminative appearance features. Thus, the data association ambiguity can be reduced surprisingly by exploiting Faster-RCNN, which means fewer hypothesis for MHT. Meanwhile, the issue of abrupt appearance changes can be addressed by modeling discriminative appearance feature based-on MHT. Many experiments on MOT benchmark show competitive performance of the proposed approach in comparison with other state-of-art tracking methods.
