A simple way to broaden objects search area for tracking methods based on discriminative correlation filters

We propose a simple way to broaden objects search area for tracking methods based on discriminative correlation filter using two window functions of different bandwidth. Testing at the VOT-2016 Challenge confirmed that this approach provided higher robustness and accuracy of tracking, comparing to standard realizations, where only one window function was used. We created a software implementation of tracking system based on the proposed approach and estimated its performance. The proposed software realization for PC platform and modern ARM platforms can track objects in real-time.
