We present a novel sampling and processing method for detecting gait events from an insole pressure sensor. Inspired by how tactile data is processed in the brain, we propose the use of timing, instead of intensity, as our event detection feature. By sacrificing the need for accurate intensity measurements, it is possible to achieve superior temporal resolution, which is arguably more important given...
Underwater acoustic communication systems need Doppler compensation for the server Doppler effects. OFDM (Orthogonal Frequency Division Multiplexing) is widely applied in the underwater acoustic communication systems. FFT is the most computational kernels in the OFDM systems. By exploring the two typical digital signal processing kernels and other basic kernels, an ASIP (Application Specific Instruction...
Virtual human motion capture data has been widely applied in virtual reality, computer animation, etc. It is important to segment the motion data into small clips automatically in order to reuse these data. In this paper, a new method of motion capture data segmentation is proposed based on kernel dynamic texture. First we model the motion capture data using kernel dynamic texture, and then on the...
We describe a real-time multiple face-tracking algorithm under highly occlusion. In order to resolve the occlusion and temporal lost problem, a robust data association + filtering procedure is proposed. The mechanism combines the census transform based block-by-block strategy to infer the occlusion state via concerning observation changes of two faces. And a robust and straightforward filtering approach...
In this paper, feature selection was carried out for multi-intelligence classification, and finds key regions. We designed different multi-intelligence tasks with BCI. SVM was used to classify and select features. The experiment reveals that a band has a greater effect on imagery intelligent tasks. And the introduced feature selection algorithm succeeded to detect key regions for multi-intelligence...
Focusing on the architecture characteristics of the new computer architecture with high-security sCPU-dBUS, this paper designs and implements an inter-subsystem data transfer mechanism based on the new high-security operating system with internal networking structure netOS-I which is only used by the sCPU-dBUS. The data transfer mechanism mainly contains inter-subsystem data transfer interface, inter-subsystem...
This study proposed the concepts, architecture, and kernel of a GroupNet system to construct a more flexible ubiquitous learning environment. GroupNet is aiming to support small-group face-to-face learning activities anywhere and anytime without sticking in traditional classroom settings and additional infrastructures. We have also implemented the application programming interface (API) for accessing...
Anti-virus experiment in vitro is a common way to screen and identify antiviral drugs. Most of the cell lines in anti-virus experiments are wall-adherent. The segmentation, recognition and counting this wall-adherent cells in micrograph successfully can cut down the time and cost of the experiment. Because of the wall-adherent cells characteristics, to segment this kind of image is much difficult...
