Optical Flow Dataset and Benchmark for Visual Crowd Analysis [article]

Gregory Schröder, Tobias Senst, Erik Bochinski, Thomas Sikora
2018 arXiv   pre-print
The performance of optical flow algorithms greatly depends on the specifics of the content and the application for which it is used. Existing and well established optical flow datasets are limited to rather particular contents from which none is close to crowd behavior analysis; whereas such applications heavily utilize optical flow. We introduce a new optical flow dataset exploiting the possibilities of a recent video engine to generate sequences with ground-truth optical flow for large crowds

Instead we focus on real-world surveillance scenarios where numerous small, partly independent, non rigidly moving objects observed over a long temporal range pose a challenge. By evaluating different optical flow algorithms, we find that results of established datasets can not be transferred to these new challenges. In exhaustive experiments we are able to provide new insight into optical flow for crowd analysis. Finally, the results have been validated on the real-world UCF crowd tracking benchmark while achieving competitive results compared to more sophisticated state-of-the-art crowd tracking approaches.

From 2D- to Stereo- to Multi-view Video

Sebastian Knorr, Aljoscha Smolic, Thomas Sikora
2007 2007 3DTV Conference  
This paper presents a new approach for generation of multiview video from monocular video. Such multi-view video is used for instance with multi-user 3D displays or autostereoscopic displays with head-tracking to create a depth impression of the observed scenery. The intention of this work is not a real-time conversion of existing video material with a deduction in stereo perception, but rather a more realistic off-line conversion with high accuracy. Our approach is based on structure from

The algorithm is tested on several TV broadcast videos, as well as on sequences captured with a single handheld camera. Finally, some simulation results will show the remarkable performance of this approach.

Video-based Bottleneck Detection utilizing Lagrangian Dynamics in Crowded Scenes [article]

Maik Simon, Markus Küchhold, Tobias Senst, Erik Bochinski, Thomas Sikora
2019 arXiv   pre-print
Avoiding bottleneck situations in crowds is critical for the safety and comfort of people at large events or in public transportation. Based on the work of Lagrangian motion analysis we propose a novel video-based bottleneckdetector by identifying characteristic stowage patterns in crowd-movements captured by optical flow fields. The Lagrangian framework allows to assess complex timedependent crowd-motion dynamics at large temporal scales near the bottleneck by two dimensional Lagrangian
more » ... In particular we propose long-term temporal filtered Finite Time Lyapunov Exponents (FTLE) fields that provide towards a more global segmentation of the crowd movements and allows to capture its deformations when a crowd is passing a bottleneck. Finally, these deformations are used for an automatic spatio-temporal detection of such situations. The performance of the proposed approach is shown in extensive evaluations on the existing J\"ulich and AGORASET datasets, that we have updated with ground truth data for spatio-temporal bottleneck analysis.
