Abstract

Due to the domain shift between images and videos, standard object detectors trained on images usually do not perform well on videos. At the same time, it is difficult to directly train object detectors from video data due to the lack of labeled video datasets. In this paper, we consider the problem of localizing objects in weakly labeled videos. A video is weakly labeled if we know the presence/absence of an object in a video (or each frame), but we do not know the exact spatial location. In addition to weakly labeled videos, we assume access to a set of fully labeled images. We incorporate domain adaptation in our framework and adapt the information from the labeled images (source domain) to the weakly labeled videos (target domain). Our experimental results on standard benchmark datasets demonstrate the effectiveness of our proposed approach.
