Audio watermark has been found to be an attractive technology for automated identification and protection of copyrighted works against unauthorized use in high-resolution optical media formats, such as Blu-ray Disc and DVD-Audio. Previous systems have been designed to operate in standalone devices without any dependence on local or wide area network connectivity. As newer generations of secure media...
At present, existing association rules mining algorithms have redundant candidate frequent itemsets and repeated computing. This paper proposes an algorithm of locating order mining based on sequence number, which is suitable for mining long frequent itemsets. In order to fast search long frequent itemsets, the algorithm adopts not only traditional down search, but also the method of locating order...
This paper proposes a novel method for planning exploration path in 3D object observation. First, we give a viewpoint quality metric, which combines the notion of mesh saliency and fuzzy nearness. Each viewpoint corresponds to a fuzzy set, and the quality of a viewpoint can be measured by fuzzy nearness between a normal fuzzy set and the ideal fuzzy set. Then, we compute an optimal viewpoint set....
This paper proposed a novel method for selecting good views in 3D scene observation. A lot of existing methods for computing viewpoint quality are based on the number of visible faces and the projected area only, so they miss the visual identity of the scene. Our method combines the notion of mesh saliency and fuzzy nearness. First, we construct a fuzzy set for a viewpoint. The elements of the set...
We propose a novel decision-feedback maximum likelihood sequence estimation, and numerically demonstrate its use in 10 GS/s 8-ASK-DQPSK (8-ASK-QPSK) systems to significantly improve the dispersion tolerance, without increasing the computation complexity exponentially with the format-level number.
In order to obtain the feature parameters of a signal, the image ridge of time-frequency domain must usually be detected. In the paper, the PSO algorithm is applied to the detection of the transform-domain image ridge. A new ridge detection algorithm is proposed, together with its specific realization process. Furthermore, this method is simulated to evaluate precision of this and the robustness of...
We consider a multiple-input multiple-output (MIMO) two-way relaying system, where two wireless terminals exchange data via a half-duplex decode-and-forward (DF) relay. The problem of optimum time-division (TD) between the multiple access (MAC) phase and the broadcast (BRC) phase is addressed in this paper. We characterize the achievable rate regions with optimum TD strategies between the two phases...
Constrained principal component (CPC) analysis of stochastic process extracts the most representative components from a given constraint subspace. It is an effective means to incorporate external information into principal component analysis (PCA) and is appealing in a variety of application areas. This paper proposes a novel autoassociative network to find optimal CPC solutions and compares the proposed...
