In clutter background, the performance of tracking target can be influenced by the factors such as illumination, camera angle. Meanwhile the target can be occluded by some obstacles in the background or be occluded by the target itself. To solve those problems, a multi-window tracking method is proposed, which represents the tracking target with several windows that each one corresponds with a tracker...
With the progress of construction technology, the modern buildings become more and more complicated and large-sized. It is difficult to avoid sudden and catastrophic emergency events for interior buildings. Hence, it is very important to establish an evacuation model to simulate evacuation behavior of pedestrians under real condition and make a scientific and effective evacuation plan. For handling...
To overcome the problems about consequence discontinuities and consequence sorting dissatisfaction of relational database-based key word retrieval, a novel data community-oriented object-level retrieval system is designed and implemented, which is based on data graph. The combination of each keyword nodes that center nodes can reach determines a community. Some corresponding adjustments are carried...
With the air fight environment getting more and more complex, the anti-jamming performance of active radar guided air-to-air missile (ARGAAM) is noticed by all countries worldwide. This paper develops a new method to plan the anti-jamming performance test for ARGAAM characteristic. The method plans the missile anti-jamming performance test by flight test and digital simulation. Finally, the anti-jamming...
Through analyzing the small UAV (Unmanned Aerial Vehicle) flight control system based on CAN (Controller Area Network) bus, the paper focuses on the study of flight control system bus architecture, and puts up an ADS-B (Automatic Dependent Surveillance-Broadcast) architecture design which is suitable for this type of UAV. Transplants the mature ADS-B system with a focus on the design of CAN bus interface,...
In view of problem that it usually lacks of fusion depth to combine moment invariants with other extraction technology on local invariant features, this article proposes the moment invariants based on SUSAN initial edge response, which provides a sort of organic integration for moment invariants and SUSAN edge detection algorithm. The combination point is to treat SUSAN initial edge response matrix...
By following Ma et al's inspiring work (or termed, Ma equivalence), this paper proposes and investigates an acceleration-level minimization scheme for motion planning of redundant robot manipulators. Such a scheme depicted in the pseudo inverse-type formulation can achieve the purpose of the minimum kinetic energy (MKE) redundancy resolution originally at the joint-velocity level, and is thus termed...
In this paper, we studied two kinds of image super-resolution algorithms based on MAP-The single frame and multi-frame based regularization technique. In multi-frame version the local adaptive regularized parameter derived from the local image features was introduced to improve the regularization performance, while insufficient considerate in single version. The algorithms adaptively update the parameter...
In this paper, it is presented that a new color image watermarking algorithm based on compressed sensing theory and chaos theory in discrete cosine transform (DCT) and singular value decomposition (SVD) domain. Initially, a color watermarking image is preprocessed by four steps i.e. Being divided into red, green and blue channels, being sparse by wavelet transform, scrambling by 1-D chaos sequence...
