Human detection in dense crowds poses to be a demanding task owing to complex background and serious occlusion. In this paper, we propose a novel real-time and reliable human detection system. We solve the human detection problem by presenting a novel cube surface model captured by a binocular stereo vision camera. We first propose a cube surface model to estimate the 3D background cubes in the surveillance...
This study examines the acoustic effect of the laryngeal cavity of female speakers on the higher vowel spectra. To do so, MRI data of vowels /a/ and /i/ obtained from three female speakers were analyzed with data from a male speaker as reference. 3D vocal-tract shapes were extracted from the MRI data and printed as solid mechanical models. Transfer functions of the models' vocal tracts were estimated...
Reconstructing 3D face models from multiple uncalibrated 2D face images is usually done by using a single reference 3D face model or some gender/ethnicity-specific 3D face models. However, different persons, even those of the same gender or ethnicity, usually have significantly different faces in terms of their overall appearance, which forms the base of person recognition using faces. Consequently,...
Augmented Reality (AR) refers to the science and technology which enables 3D/2D computer graphics to overlay video frames in real time so as to add contextual information to deepen people's understanding of the real scene. In particular, outdoor AR as an emerging technology opens up new possibilities and applications for Location Based Services (LBS). As with the increasing amount of 3D city models...
Getting good viewpoints has been considered important for promoting the efficiency when investigating a model. Many view selection methods therefore have been proposed. In particular, measuring semantic meaning of the model features through segmentation is regarded more effective to get optimal viewpoints. Unfortunately, the semantic meanings of the model are usually obtained through experiences,...
