We focus on the pose of persons standing directly on the red carpet. A web application is presented allowing collaborative work to confirm or modify already pre-localised body keypoints given from the method presented in [Ca17]. These annotations helped to quickly define ground truth for the subsequent evaluation of several hundreds of persons standing on a red carpet. An own evaluation formalism is presented that adopts to the size of the respective keypoints. The TV studio data set includes coarsely defined body and head poses. Using the angular information, we are able to quantitatively define the optimum head pose angle range and limitations of facial keypoint determination.
- ReportUsing Audio for Detecting Covered Users in Front of Public Displays(2022) Foldenauer, Katarina; Plischke, Tobias; Strauß, Luca; Viehmann, Eike; Koch, MichaelPublic displays have become more and more ubiquitous in recent years. Both for managing public display networks and for doing research in this field it is an important issue to automatically detect what is happening in front of these screens. This often is done with the help of depth cameras. However, measurement errors can occur due to occlusion or underexposure. In our research we looked into the idea to support the detection of concealed persons using audio information. A se-ries of laboratory experiments showed that audio recordings can be used to detect concealed per-sons. This can be used in existing installations to minimize occlusion error in visual recordings.
