Crowd analysis by automated visual surveillance represents a challenging task in many practically relevant scenarios. In this paper we address the problem of capturing relevant correlated movement within a line formed by waiting pedestrians to estima

The task of large-area visual monitoring for the protection of critical and public infrastructures calls for reliable automated visual surveillance systems. Reliability in this context implies that a high detection accuracy of critical events shall b

We propose a new feature descriptor for action recognition and crime detection using computation of feature relations in the spatio-temporal domain. The novelty of this approach is the computation of similarity of body-parts during movement of the bo

In this paper, we evaluate a new algorithm for pedestrian detection using a relational feature model (RFM) in combination with histogram similarity functions. For histogram comparison, we use the bhattacharyya distance, histogram intersection, histog

Pedestrian detection has been used with the help of various local features in still images such as histograms of oriented gradients (HOG), local binary patterns (LBP) and more recently, the histograms of optical flow (HOF). In order to improve the ro

Vision based fall detection solutions support elderly who live alone in their homes. For people falling down and not being able to stand up on their own again, such a fall is a major risk. In this work, we show a person detection approach using a rel

In this paper we evaluate similarity functions for histograms such as chi-square and Bhattacharyya distance for different color spaces such as RGB or L*a*b*. Our main contribution is to show the performance of these histogram-based similarity functio
