Query: Active Mining of Parallel Video Streams   The practicality of a video surveillance system is adversely limited by the
amount of queries that can be placed on human resources and their vigilance in
response. To transcend this limitation, a major effort under way is to include
software that (fully or at least semi) automatically mines video footage,
reducing the burden imposed to the system. Herein, we propose a semi-supervised
incremental learning framework for evolving visual streams in order to develop
a robust and flexible track classification system. Our proposed method learns
from consecutive batches by updating an ensemble in each time. It tries to
strike a balance between performance of the system and amount of data which
needs to be labelled. As no restriction is considered, the system can address
many practical problems in an evolving multi-camera scenario, such as concept
drift, class evolution and various length of video streams which have not been
addressed before. Experiments were performed on synthetic as well as real-world
visual data in non-stationary environments, showing high accuracy with fairly
little human collaboration.
