We propose an integral three-dimensional (3D) display system with a wide viewing zone and depth range using time-division eye-tracking technology. In the proposed system, optical (OVZ) is narrowed to size that only covers eye increase light ray density lens array long focal length. addition, low crosstalk respect viewer’s movement constructed by forming combined OVZ (COVZ) both eyes through dis...

The atmosphere of the Sun is highly structured and dynamic in nature. From the photosphere and chromosphere into the transition region and the corona plasma-β changes from above to below one, i.e. while in the lower atmosphere the energy density of the plasma dominates, in the upper atmosphere the magnetic field plays the governing role — one might speak of a " magnetic transition ". Therefore ...

We present a method for estimating the distance between a camera and a human head in 2D images from a calibrated camera. Leading head pose estimation algorithms focus mainly on head orientation (yaw, pitch, and roll) and translations perpendicular to the camera principal axis. Our contribution is a system that can estimate head pose under large translations parallel to the camera’s principal ax...
