With the development of depth camera technology, it is feasible to get high quality color and depth images synchronously in real time. Thus, RGB-D-based applications are becoming more and more popular, such as pedestrian detection in RGB-D data. As the key point in this application is to search for better descriptions, in this paper we propose a new feature descriptor, Pyramid Depth Self-Similarities...
We address the problem of staircase detection, in the context of a navigation aid for the visually impaired. The requirements for such a system are robustness to viewpoint, distance, scale, real-time operation, high detection rate and low false alarm rate. Our approach uses classifiers trained using Haar features and Ad-aboost learning. This first stage does detect staircases, but produces many false...
This paper introduces a new method for streamed action recognition using Motion Capture (MoCap) data. First, the histograms of action poses, extracted from MoCap data, are computed according to Hausdorf distance. Then, using a dynamic programming algorithm and an incremental histogram computation, our proposed solution recognizes actions in real time from streams of poses. The comparison of histograms...
