Occlusions are challenging issue for robust visual tracking. In this paper, motivated by the fact that a tracked object is usually embedded into context that provides useful information for estimating the target, we propose a novel tracking algorithm named Tracking with Context Prediction (TCP). The context here includes the neighboring objects and specific(More)
Sentiment analysis in social media has attracted significant attention. Although researchers have proposed many methods, a single method is hard to meet requirement in industrial applications. In this paper, based on massive data of Tencent and industrial practice, we present a mul-tilayered analysis system (MAS) on social media. The system is composed of(More)
Traditional mean shift method has the limitation that could not effectively adjust kernel bandwidth to represent object accurately. To address this problem, in this paper, we propose a novel contour tracking algorithm using a determined binary level set model (DBLSM) based on mean shift procedure. In contrast with other previous work, the computational(More)
