摘要
En 中文
Correlation filters combined with deep features have delivered impressive results in visual tracking task. However, existing approaches treat deep features produced by different network layers independently, limiting their representation power. To address this issue, this article proposes a multi-task deep dual correlation filters (MDDCF) based method for robust visual tracking. First, a new multi-task learning scheme is designed to take full advantage of the multi-level features of deep networks, where target representation with individual features is regarded as a single task. As such, the interdependencies between different levels of features can be better explored. Second, we reformulate the objective function of the dual correlation filters and propose a new alternating optimization method, allowing joint training of the correlation filters and network parameters. Third, we design an effective object template update scheme which can well capture the target appearance variations. Extensive experimental evaluations on seven benchmark datasets show that the proposed MDDCF tracker performs favorably against state-of-the-art methods.
