As a new branch of multi-models method, Variable Structure Multiple Models (VSMM) approach is a hot topic, which involves target tracking, fault detection, etc. In this paper, it analyzes VSMM method in depth, at first. Then, it introduces three kinds of essential idea of Model Set Adaptive (MSA) being the kernel of VSMM, respectively. In succession, three typical and practical algorithms of VSMM...
Perceptual Watermarking should take full advantage of the results from human visual system (HVS) studies. Just noticeable difference (JND), which refers to the maximum difference that the HVS does not perceive, gives us a way to model the HVS accurately. In this paper, we exploit a combined JND model which represents additional accurate perceptual visibility threshold profile to guide watermarking...
Perceptual watermarking should take full advantage of the results from human visual system (HVS) studies. Just noticeable distortion (JND), which refers to the maximum distortion that the HVS does not perceive, gives us a way to model the HVS accurately. In this paper, another very important aspect affecting human perception, visual saliency, is introduced to modulate JND profile. Based upon visual...
Muscle fatigue is an unavoidable problem when electrical stimulation is applied to paralyzed muscles. The detection and compensation of muscle fatigue is essential to avoid movement failure and achieve desired trajectory. This work aims to predict ankle plantar-flexion torque using stimulus evoked EMG (eEMG) during different muscle fatigue states. Five spinal cord injured patients were recruited for...
Under the guidance of the theories of Complex Adaptive System and Artificial Societies, modeling and simulation of international politics evolution in crisis was studied. The Model of International Politics Evolution (IPEM) in crisis based on Agent was built. The function and architecture of IPEM were introduced. Individual Agent, including Nation Agent, International Organization Agent and Environment...
Perceptual watermarking for video needs to take full advantage of the results of human visual system (HVS) studies. Just noticeable distortion (JND), which refers to the maximum distortion that the HVS does not perceive, gives us a way to model the HVS accurately. Since motion is a specific feature of video, estimation of the JND profile for video needs to take into account the temporal HVS properties...
