An iterative method based on the block matching collaborative filtering is proposed for image interpolation. Unlike the conventional interpolation methods, the proposed method first utilizes the wavelet-based linear interpolation method to generate an initial estimate of the original image. Then the observation constraint provided by the given low-resolution image is enforced on the estimate to produce a combined estimate of the high-resolution image. In order to reduce the distortion of the combined estimate, the block matching collaborative filtering is exploited. Repeating the observation constraint and filtering process until the resulting image satisfying the stop criterion. Experimental results show that the proposed method obtains better performance than some existing interpolation methods.
Text categorization has been widely studied for years. However, conventional plain text categorization approaches which work good in plain text behave poor when they are simply applied to enriched format texts. An cat...

Multiple independent spanning trees have applications to fault tolerance and data broadcasting in distributed networks. There is a conjecture on independent spanning trees: any n-connected graph has n independent spanning trees rooted at an arbitrary vertex. The conjecture has been confirmed only for n-connected graphs with n=4, and it is still open for arbitrary n-connected graphs when n ≥ 5. In this paper, we provide a construction algorithm to find n independent spanning trees for the n-dimensional twisted-cube TN n , where N denotes the number of vertices in TN n . And for n ≥ 3, the height of each independent spanning tree on TN n is n+1.
By using virtual instrument technology, a direct digital control bioreactor is developed, which is able to be remote controlled through internet. Mathematical model of the bioreaction system is developed, which is use...

The algorithm applied to video watermark based on HVS is rare recently, but adaptively selecting the embedding position and the embedding strength according to the host(such as videos, images etc.) is necessary,which can make robustness and invisibility best balanced. This article gives a new algorithm about digital video watermarking based on HVS,which makes digital video watermark greatly improved.
