Network in network based weakly supervised learning for visual tracking
We propose a novel tracking method using a deep network, i.e. Network in Network (NIN).A method to transfer features learned from NIN on the source tasks to the tracking tasks.The samples are simultaneously utilized to address the drifting problem. One of the key limitations of the many existing visual tracking method is that they are built upon low level visual features and have limited predictability power of data semantics. To effectively fill the semantic gap of visual data in visual tracking with little supervision, we propose a tracking method which constructs a robust object appearance model via learning and transferring mid level image representations using a deep network, i.e. Network in Network (NIN) First, we design a simple yet effective method to transfer the mid level features learned from NIN on the source tasks with large scale training data to the tracking tasks with limited training data. Then, to address the drifting problem, we simultaneously utilize the samples collected in the initial and most previous frames. Finally, a heuristic schema is used to judge whether updating the object appearance model or not. Extensive experiments show the robustness of our method.
