In the current broadband multimedia applications, researchers and practitioners have mainly focused their designs on coping with static or slowly evolving traffic demands. Even though many such applications involve fast moving terminals, fast moving traffic conditions have not yet been taken into account which results in unrealistic simulations. It is therefore imperative to design a new channel simulation...
This paper presents a new kind of Chinese text encoding method based on Chinese word, and establishes a new Chinese document format which deals with the automatic segmentation issue. This method makes word the smallest information unit. Chinese text analysis does not rely on segmentation by the method. On this word platform, N-gram and word co-occurrence statistical analysis are combined to carry...
At present researches on Chinese keyword extraction mainly focus on automatic segmentation which is a pretreatment problem. This paper presents a kind of Chinese encoding method based on word platform, and establishes a new Chinese document format in computer. This method makes word the smallest information unit. Chinese keyword extraction does not rely on segmentation by this new method. Thereby...
A scene-based nonuniformity correction (NUC) algorithm for infrared focal plane arrays (IRFPA) is presented. In this algorithm, the infrared image sequence is decomposed by utilizing the discrete sequence wavelet transform. The corresponding statistics are calculated, and then the offset and the gain coefficients for IRFPA NUC are achieved ultimately. The algorithm achieves good NUC capability, which...
