Introduction This poster presents how we have used the ARToolKit to develop a cheap and low cost 3DOF (degrees of freedom) hand tracker, allowing us to use a video camera (see figure 2) mounted on the head to track the motion of the hands of the user (see figure 1) as real world X, Y, Z values. This tracker is most useful when working in mobile outdoor environments, as traditional tracking tech...

Severe weather prediction, such as tropical cyclone (TC) forecast is a typical data mining and forecasting problem that involves high level data manipulation and interpretation of meteorological information such as satellite pictures and other meteorological observation data. In this paper, we present a fully automatic and integrated system known as "ATOMOSPHER" Automatic Track Mining and Objec...

The launch of SELENE, which acquired the first direct tracking data over the farside of the Moon by the use of 4-way Doppler data between a relay satellite and the main satellite, has resulted in a dramatic improvement of the knowledge of the global lunar gravity field[1,2]. In addition to the 4-way Doppler data, same-beam differential VLBI data between the two sub-satellites and two stations o...

This contribution reassesses progress in the development of satellite laser ranging (SLR) technology and its scientific and societal applications in South Africa. We first highlight the current global SLR tracking stations within the framework of the International Laser Ranging Service (ILRS) and the artificial satellites currently being tracked by these stations. In particular, the present wor...

against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (ins/radar). this filter involves the concept of residual-based adaptive estimation and adaptive fading kalman filter and tunes dynamically the fil...

In order to assess the influence of breed on the vertebral heart scale (VHS) of dogs, the VHS was measured and compared in left to right (LL) and right to left lateral (RL) views. For all dogs (n=56), the mean VHS on the RL radiographs [9.7 vertebra (v)] was significantly larger than the mean VHS on the LL radiographs (9.6 v) (p=0.047). Doberman dogs had higher mean values of the VHS in LL (9.9...

Video satellites have recently become an attractive method of Earth observation, providing consecutive images the Earth’s surface for continuous monitoring specific events. The development on-board optical and communication systems has enabled various applications satellite image sequences. However, video-based target tracking is a challenging research topic in remote sensing due to its relativ...
