Transformer Feature Enhancement Network with Template Update for Object Tracking

Sensors (Basel). 2022 Jul 12;22(14):5219. doi: 10.3390/s22145219.

Abstract

This paper proposes a tracking method combining feature enhancement and template update, aiming to solve the problems of existing trackers lacking global information attention, weak feature characterization ability, and not being well adapted to the changing appearance of the target. Pre-extracted features are enhanced in context and on channels through a feature enhancement network consisting of channel attention and transformer architectures. The enhanced feature information is input into classification and regression networks to achieve the final target state estimation. At the same time, the template update strategy is introduced to update the sample template judiciously. Experimental results show that the proposed tracking method exhibits good tracking performance on the OTB100, LaSOT, and GOT-10k benchmark datasets.

Keywords: feature enhancement; object tracking; template update strategy; transformer architectures.
