    The biomedical signals are often corrupted by noise in their acquisition or transmission resulting in lower Signal to Noise Ratio (SNR), which brings problematic obstacles to successive biomedical signal processing. So suppressing noise and improving SNR effectively is an essential procedure and key issue in the research on biomedical signal processing. In this paper, we propose a novel multi-mode...

    A structured light system composed of the digital devices and phase-shifting method is widely used for the accurate three-dimension profile measurement. However, the nonlinear gamma error and harmonics error of the digital devices, especially the projector, will cause the captured fringe patterns to be non-sinusoidal waveforms, which lead to an additional phase error and therefore measurement erro...

    Support Vector Machines are an effective form of binary-class classification algorithm. To enhance the utilization of text structural features for information extraction, which are greatly restricted by the Hidden Markov Model (HMM), this paper proposes a support vector machine multi-class classification based on Markov properties to extract the information from a citation database. The proposed m... View full abstract»

    This paper presents a method for automated extraction of MCP joints in infrared images of hands. Based on averaged anatomical structure and landmarks of human hands, three different models are proposed to estimate the regions of MCP joints of human hand: rectangle model, ellipse model and circle model. In addition, to evaluate the accuracy and validity of the three models, we propose a new way to ... View full abstract»

    Malware, such as Trojan Horse, Worms and Spy ware severely threatens Internet. We observed that although malware and its variants may vary a lot from content signatures, they share some behavior features at a higher level which are more precise in revealing the real intent of malware. This paper investigates the technique of malware behavior extraction, presents the formal Malware Behavior Feature... View full abstract»

    The left and right inferior colliculus (IC) are interconnected with each other by the commissure of inferior colliculus (CoIC). So far, little has been known about its role in the auditory information processing and integration between the two ICs in real time. In this study, we examined the changes in the best frequency (BF) of neurons in one side IC (ICRec) during activation of CoIC by focal ele... View full abstract»

    Identifying the subject's simple judging states from fMRI data is the basis of studying complex logical relationship and has great theoretical significance. In this paper, we study judging states from fMRI data in terms of logical recognition classifications. We found that the ROI (Regions of Interest) regions played an important role in visual recognition task and identified what ROI regions were... View full abstract»
