The desire to have intuitive, seamless 3D interaction fuels research into new 3D interaction approaches. However, research continues to rely on Brunelleschi’s perspective to provide a sense of visual depth to create a 3D graphical display. The interactive control space has been mapped directly into the 3D virtual display space without much thought about the effect that perspective distortion ha...

In this article, we evaluate the improvement in sign recognition that can be achieved with 3D tracking, compared to recognition with image plane tracking. Experiments are shown using a pair of stereo cameras, from which 3D positions of the segmented hands are estimated by triangulation between the left and right cameras. A sign classifier is trained on a set of 37 different NGT signs using 2D a...

In this paper, we propose a novel 3D polarimetric computational integral imaging system by using polarization diversity of objects under natural illumination conditions. In the system, the measured Stokes polarization parameters are utilized to generate degree of polarization images of a 3D scene. Based on degree of polarization images and original 2D images, we utilize a modified computational...

This report is concerned with understanding the interplay between 3D face reconstruction and recognition. We provide analysis for the effect of adaptive sparse 3D reconstructions on recognition rate. This work illustrates that, for 3D face recognition, a proper mesh containing nearly 2% of the facial information and about 5 times the initial/root mesh provides similar recognition rate as one wi...

The main goal of this study is determination the effect of GCR (gray component replacement) levels on colorimetric characteristics of color proof. To determine the effect of GCR levels on colors of color proofs, a comparison of 2D and 3D color gamuts depending on GCR level have been performed. In addition to obtain better assessment of the effect of GCR levels on color gamut were calculate volu...

The integration of three-dimensional (3D) data with infrared thermography has received much attention for its potential use as input data for building energy simulations. Therefore, researchers have proposed methods to integrate 3D data with infrared thermography obtained by different sensors. These studies show the potential of the integration of 3D data and infrared thermography using various...
