چکیده

In this work we propose to train boundary detectors using weakly supervised annotations. We propose and evaluate multiple strategies to generate annotations fusing different sources, such as unsupervised image segmentation [2], object proposal methods [10, 5], and object detectors [3, 6] (trained on bounding boxes). Figure 5 illustrates the examples of the proposed weakly supervised boundary annotations, these extend the example in Figure 4 of the main paper. See Section 5 of the main paper for more details.

Weakly Supervised Object Localization with Progressive Domain Adaptation Supplementary Material

In this supplementary material, we present three additional results to complement the paper. First, we report detailed quantitative evaluation on the PASCAL VOC and ILSVRC object detection datasets. Second, we show additional qualitative detection results on the VOC 2007 dataset. Third, we analyze the errors of three variants of the proposed approach and show relative contributions from each co...

State-of-the-art learning based boundary detection methods require extensive training data. Since labelling object boundaries is one of the most expensive types of annotations, there is a need to relax the requirement to carefully annotate images to make both the training more affordable and to extend the amount of training data. In this paper we focus on learning object boundaries in a weakly ...
