Abstract

Labeling video data is an essential prerequisite for many visionapplications that depend on training data, such as visualinformation retrieval, object recognition, and human activitymodeling. However, manually creating labels is not onlytime-consuming but also subject to human errors, and eventually,becomes impossible for a very large amount of data (e.g. 24/7surveillance video). To minimize the human effort in labeling, wepropose a unified multi-class active learning approach forautomatically labeling video data. The contributions of this paperinclude extending active learning from binary classes to multipleclasses and evaluating several practical sample selectionstrategies. The experimental results show that the proposedapproach works effectively even with a significantly reduced amountof labeled data. The best sample selection strategy can achievemore than a 50% error reduction over random sample selection.
