Tracking with Deep Neural Networks

We present deep neural network models applied to tracking objects of interest. Deep neural networks trained for general-purpose use are introduced to conduct long-term tracking, which requires scale-invariant feature extraction even when the object dramatically changes shape as it moves in the scene. We use two-layer networks trained using either supervised or unsupervised learning techniques. The networks, augmented with a radial basis function classifier, are able to track objects based on a single example. We tested the networks tracking capability on the TLD dataset, one of the most difficult sets of tracking tasks and real-time tracking is achieved in 0.074 seconds per frame for 320x240 pixel image on a 2-core 2.7GHz Intel i7 laptop.
