Feature matching is not only a fundamental but also a difficult problem in computer vision. Compared with the traditional perspective images, fish-eye images have more serious non-linear distortion and the illumination changing in different regions, which make feature extraction and matching more difficult. The traditional methods on image matching are most based on textural features

The flyers, such as stealth aircraft, Anti radiation Missile, and Cruise Missile and so on, are widely used in modern war. The radar echoes of them are much weaker than those of traditional flyers. The signal to noise ratio(SNR) is too low to detect target reliably with general algorithms. Although by increasing the transmitter power,

Data-intensive applications, most of which are with strong data dependencies, are widespread in scientific computing area such as bioinformatics, financial management, production scheduling, engineering and so on. Problems which can be decomposed into repeated sub problems and are with optimal substructure can be solved efficiently by the dynamic programming algorithm. However, due to the sharp

A Mobile Ad Hoc Network (MANET) is a multi-hop system constructed by a set of mobile terminals dynamically and without the support of existing infrastructure. Because nodes in the network can move freely, MANETs can organize a network quickly and are very strong. With the development of network technology and high demands of users, providing
