Ground plane detection in 3D scenes for an arbitrary camera roll rotation through “V-disparity” representation

Authors: Piotr Skulimowski, Mateusz Owczarek, Paweł Strumiłło in: 2017 Federated Conference on Computer Science and Information Systems Abstract: In this paper we proposed a fast method for detecting the ground plane in 3D scenes for an arbitrary roll angle rotation of a stereo vision camera. The method is based on the analysis of the disparity map and its… Continue Reading Ground plane detection in 3D scenes for an arbitrary camera roll rotation through “V-disparity” representation

Comparison of HRTFs from a Dummy-Head Equipped with Hair, Cap, and Glasses in a Virtual Audio Listening Task over Equalized Headphones

Authors: Wersényi, György; Répás, József in: Proceedings of the 142nd Convention of the Audio Engineering Society Abstract: Head-Related Transfer Functions (HRTFs) are frequently used in virtual audio scene rendering in order to simulate sound sources at different spatial locations. The use of dummy-head HRTFs (also referred as generic sets) is often criticized because of poor localization performance, leading… Continue Reading Comparison of HRTFs from a Dummy-Head Equipped with Hair, Cap, and Glasses in a Virtual Audio Listening Task over Equalized Headphones
