Target image database is of great significance in SAR automatic target recognition (ATR). Recently, some convenient and low cost approaches of database simulation were proposed. However, the similarity between virtual SAR images obtained by these simulation approaches and real SAR images is still under study. To solve this problem, we will model the virtual target with three-dimensional (3D) modeling...
To investigate the electroencephalogram (EEG) records in Chinese Han ethnic Alzheimer's disease (AD) patients, a nonlinear feature investigation of the resting EEG was carried out on local AD (NINCDS-ADRDA criteria) patients. The age-matched normal elderly subjects served as controls. An estimator of mutual information entropy was introduced to quantify the nonlinear characteristics of time series...
The aim of this paper is to estimate muscle fatigue by using wavelet analysis method in SEMG signal analysis. A signal acquisition system is designed and forearm muscle fatigue experiments under static and dynamic contractions are performed. The wavelet analysis method is proposed to group the wavelet coefficients of SEMG signal into high frequency-band (100Hz-350Hz) and low frequency-band (13-22Hz)...
