In order to realize the copyright protection of audio information and improve the security of the watermarking algorithm, a secure robust audio watermarking algorithm via quantization of the random correlation coefficients in lifting wavelet transform domain and QR decomposition is proposed Firstly, lifting wavelet transform is performed on the audio data, the approximate components are mapped into...
Deep learning has recently exhibited good performance in many applications. The convolution neural network is an often-used architecture for deep learning and has been widely used in computer vision and audio recognition, and outperformed other related handcraft designed feature in recent years. These techniques compared to other artificial intelligence algorithms and handcraft features need extremely...
With the worldwide popular of the stereoscopic film "Avatar", stereoscopic video has become the focus of the industry, and also greatly promoted the development of stereoscopic video shooting technology. On the market nowadays, the stereoscopic video shooting cradle head gets horizontal mostly through the manual setting of the independent knobs and the legs of the tripod by observing the...
This paper proposes a novel feature fusion method for the protein subcellular multiple-site localization prediction. Several types of features are employed in this novel protein coding method. The first one is the composition of amino acids. The second is pseudo amino acid composition, which mainly extract the location information of each amino acid residues in protein sequence. Lastly, the information...
Facial shape cloning (FSC) is a task aiming to simulate the plastic surgery result of reshaping a user's face to bear analogy to a model's facial appearance. Facial cosmetic reproducing (FMR) is another task intending to emulate the transfer of the cosmetic effects on a model face to the user's face. This paper presents a method which can perform both the FSC and the FMR. This proposed method features...
It is a hard work for the traditional k-means algorithm to perform data clustering in a large, dynamic distributed wireless sensor networks. In this paper, we propose a distributed k-means clustering algorithm, in which the distributed clustering is performed at each sensor with the collaboration of its neighboring sensors. To extract the important features and improve the clustering results, the...
Smartphones nowadays are used not only for communication but also for many emerging applications, such as m-commerce. And, biometric methods can provide promising applications to secure mobile devices. In this paper, we propose a novel authentication mechanism using the information collected from the accelerometer sensor and touchscreen of the smartphone. We design an authentication mechanism that...
In this paper, to integrate android systems, intelligent computing and web service on an intelligent mobile web service computing systems for bioinformatics is proposed. That is, users can send parameters to control the intelligent computing system under Matlab/C#/Java and query from clientside to server-side in the proposed bioinformatics systems with their android phone. Besides, the proposed system...
This paper enhances the hierarchical fuzzy model to deal with the classification problems by adopting evolutionary genetic algorithm (GA) with a modified artificial bee colony (ABC) algorithm. Traditionally, fuzzy classifier could not provide a sufficiently high classification rate in higher feature dimension with few rules. In the literature, the genetic algorithm can take advantage from the global...
The problem of recovering low-rank matrix from only a subset of observed entries is known as the matrix completion problem. Many problems arising in compressive sensing, image processing, machine learning, can be usefully cast as this problem. In this paper, we propose an extended linearized augmented Lagrangian method of multipliers for the problem, and prove its global convergence. We show that...
This paper is concerned with approximate optimal formation control for multiple nonlinear autonomous agents based on iterative method. By designing some concatenation vectors, a whole multi-agent system is obtained, and the original formation control problem is transformed into a classic tracking problem. Based on the classic optimal tracking control theories, the optimal formation control problem...
This paper studies the vibration control problem for systems with delayed state under persistent disturbances. In order to simply the vibration control problem for system with delayed states, a free-delayed-state method is proposed to reform the original problem into an equivalent optimal regulate problem with delay-free ones. Then, an approximate optimal vibration controller is obtained from a Riccati...
This paper presents an intelligent consensus-based cooperative formation control using recurrent fuzzy wavelet cerebellar-model-articulation-controller (RFWCMAC) for a team of uncertain multiple ballbots. The dynamic model of each ballbot is formulated as one multivariable second-order underactuated dynamic system model, and the multirobot system is modeled by graph theory. By online learning the...
In this paper, we present controller design for strict feedback nonlinear systems with full state constrains. An Integral Barrier Lyapunov Functionals (iBLF) is employed to obtain the adaptation law and the controllers. Compared with existing methods, the unknown parameters are considered in the system. Under the proposed iBLF-based control, we show that tracking errors are achieved without violation...
Recruitment is a significant process that affects to organizational performance. Recruiters expect to meet the most appropriate employee for the right job, but a large number of resumes make more difficult to their decision. For this reason, this paper proposed the recommender system to support recruiter in the decision and manage recruitments. The two techniques include matching and collaborative...
The channel estimation algorithm which has excellent performance is necessary for Single Carrier Frequency Division Multiple Access (SC-FDMA) system. The traditional Least Square (LS) algorithm and Linear Minimum Mean-Square (LMMSE) algorithm exist many problems. The problem of the LMMSE algorithm which is too complex is found to be applied effectively by researching LMMSE algorithm. The traditional...
