Aiming at shortcomings of traditional image retrieval systems, a new image retrieval approach based on color features of image combining intuitive fuzzy theory with genetic algorithm is proposed. Each image is segmented into a constant number of sub-images in vertical direction. Color features are extracted from every sub-image to get chromosome coding. It is considered that fuzzy membership and intuitive fuzzy hesitancy degree of every pixel＇s color in image are associated to all the color histogram bins. Certain feature, fuzzy feature and intuitive fuzzy feature of colors in an image, are used together to describe the content of image. Efficient combinations of sub-image are selected according to operation of selecting, crossing and variation. Retrieval results are obtained from image matching based on these color feature combinations of sub-images. Tests show that this approach can improve the accuracy of image retrieval in the case of not decreasing the speed of image retrieval. Its mean precision is above 80 %.

The popularity of wireless communication networks makes them an attractive target to the creators of worms and other malicious code. Indeed, recently a number of worms designed specifically to spread via these wireless networks have emerged. Based on the epidemic theory, this paper proposes a general model which predicts how a worm propagates through a wireless ad hoc network. Then the differential equations of the model is presented and a necessary condition for worms to spread in these networks is derived, which may be useful in designing a secure wireless ad hoc network. Simulation results show that the process of worm propagation in these wireless networks is sensitive to the deployment density of nodes and the energy consumption of nodes. Therefore, our study can provide insight into deriving a general model to characterize worm propagation in wireless ad hoc networks. & copy;2009 IEEE.
