In this paper, image multi-scale edge detection based on anti-symmetrical wavelet is given detailed in theory. Namely convolution operation property which anti-symmetrical wavelet transform bears is deduced, and function of which anti-symmetrical biorthogonal wavelet transform works as differential operator is analyzed. Algorithm of wavelet decomposition in which multi-scale edge can be detected is...
The differentiated services (DiffServ) model relies on the per hop behavior (PHB) in each network device to treat packets differently based on packet headerspsila DSCP (DiffServ code point). For each DiffServ compliant router, the scheduling algorithm is critical in implementing PHBs, according to which packets are forwarded. In this paper, we propose the parallel maximum urgency first (PMUF) scheduling...
Text classification is an important task of data mining. Existing algorithms, which based on vector space models, does not considered concept similarities among words, so the accuracy of traditional text classification cannot guarantee. To solve the problem, this paper proposes a new text classification algorithm in Chinese text processing based on concept similarity. The contributions of the paper...
