LTE License-Assisted Access (LTE-LAA) in unlicensed spectrum has drawn a lot of attention due to its appealing data traffic offloading potential. However, the coexistence of LTE and WiFi technologies in the same unlicensed bands needs careful design to avoid severe interference between them. In this paper, we propose a coexistence scheme to create opportunities for LTE-LAA small cells and WiFi devices...
Aiming at several common drawbacks of existing gaze tracking algorithm which is based on image processing technology: low accuracy, low suitability and high requirement of device, this paper presents an improved gaze tracking method based on the human eye model. The vision scatter model is established by studying the relationship among the center of iris, inner corner of eye and the gaze direction...
An adaptive motion tracking scheme based on spatial correlation is presented. By the property of the magnitudes of motion vectors (MVs) of neighboring blocks, the current MV is first estimated as the initial search centre which may be close to the global minimum, and then refined by certain fast search algorithm. In order to avoid error propagation, those frames whose distortions exceed tolerance...
