Accurate and efficient face authentication method has been a hot research field for a long time. The main research attention of this paper was directed toward studying the face authentication based on RGB color image and depth image, which is captured by Kinect device. Firstly, the 121 face features was extracted based on Candide-3 face model. Secondly, this paper built a face mask using the characteristics...
Videos are an important source of information and require extremely computation expensive analysis in order to understand the high level semantics. The computational difficulties in extracting embedded information and bridging the semantic gap present the major challenges in interoperability, scalability and real-time response of video analytic systems. In this paper, we propose an intelligent video...
Summary form only given. As a highly intensive and subnanosecond pulse X-ray point source, X-pinch plasma could find many potential applications. A pulsed power generator (500 kV, 400 kA, 100 ns) was constructed and used as the power source of an X-pinch. The X-pinch load was made of two 25-??m Mo wires. The temporal and spatial X-ray emission from the X-pinch was studied by using diamond photoconducting...
Firstly, based on the principle of binocular vergence eye movements ,a new type of method about field fixed point landing of the Subminiature robot helicopter is put forward. Secondly, according to oculomotor neural pathways, the oculomotor control system model is established. Then the control model of SHR landing system is discussed in detail. Some key problems about the control system are stressed...
This paper presents a fully automatic 3D-modelings-process of the landscape data obtained by the High Resolution Stereo Camera (HRSC) assembled on a airplane. The input of this 3D-modellingsprocess is the huge 2.5D point-clouds resulted from the photogrammetric preprocessing and the output is a group of simplified colored meshes. The 3D-modelingsprocess consists of six steps: tilling with overlap,...
