This paper presents a robust and fully-automatic human motion tracking system without motion priors information using a camera in a fixed location. Bottom-up estimation approaches have recently been applied to such tasks with some success. However, the performance of these approaches is limited by the difficulty of building an effective appearance model. In particular, the appearance model must be...
Based on the selected chemical and physical properties of amino acids, a dynamic 3-D graphical representation of protein sequences is outlined. We introduce the numerical characterization of protein graphs as descriptors to analyze and compare the nine ND5 proteins, and the results consist with the known fact of evolution. The graph of protein sequences have good visibility, the approach is simple,...
For the inevitable factors in the practical scene such as illumination chance and background interference, a new method is obtained to achieve the detection of human movement in this paper. This algorithm can remove most of the shadow and apply Gaussian filter to reduce interference. Then the moving targets under different conditions can be accurately tracked by combination of tracking algorithm and...
Electroencephalographic (EEG) activity was recorded in normal adults during a three sessions' paradigm, including eyes-closed (EC), eyes-open (EO) resting condition with binocular fixation on a center cross, and a visual attention task. In attention task, subjects were required to keep binocular fixation on a center cross, focus on right or left visual field per block, and respond to the infrequent...
The effects of visuospatial selective attention on information processing have been investigated by means of high-density event-related brain potentials (ERP) while the subjects were instructed to covertly attend to one side of the visual field with fixation on the center of the screen. Previous studies have demonstrated the attention-related modulation of the P1 (scalp-positive waves from 90-130...
This article introduces the property of magnetic field distribution and application of TMS developed by BJUT. The TMS generates time-varying magnetic field to stimulate the particular area in human brain. To obtain the distribution of magnetic density, we carried out survey by utilizing a Gauss meter, from three aspects: the distribution of magnetic density in axial direction, in radial direction...
In this paper we propose a method for estimating human skeleton proportions automatically from two-dimensional (2D) joint locations extracted from a monocular video. Unlike many other methods where the three-dimensional (3D) human postures are pre-known or posture estimations are required, the proposed method does not require correct posture recoveries for the purpose of acquiring the human skeleton...
A motion trend analysis (MTA) system is proposed for 3D human motion reconstruction from uncalibrated monocular video sequences. In this paper, a method named Motion Level Control is proposed to improve the accuracy and efficiency of the MTA system in human translation reconstruction. This method provides automatic assistance in detecting and further amending 3D motion information on transformation...
