Abstract:
Single object tracking based on deep learning has achieved the advanced performance in many applications of computer vision. However， the existing trackers have certain limitations owing to deformation， occlusion， movement and some other conditions. We propose a siamese attentional dense network called SiamADN in an end-to-end offline manner， especially aiming at unmanned aerial vehicle （UAV） tracking. First， it applies a dense network to reduce vanishing-gradient， which strengthens the features transfer. Second， the channel attention mechanism is involved into the Densenet structure， in order to focus on the possible key regions. The advance corner detection network is introduced to improve the following tracking process. Extensive experiments are carried out on four mainly tracking benchmarks as OTB-2015， UAV123， LaSOT and VOT. The accuracy rate on UAV123 is 78.9%， and the running speed is 32 frame per second （FPS）， which demonstrates its efficiency in the practical real application.
