Quantization Errors of fGn and fBm Signals (2009)
Li, Zhiheng, Li, Li, Chen, Yudong, Zhang, Yi
In this Letter, we show that under the assumption of high resolution, the quantization errors of fGn and fBm signals with uniform quantizer can be treated as uncorrelated white noises.
Principal Component Analysis of Fractional Brownian Motion (2008)
Li, Li, Li, Zhiheng, Zhang, Yi, Chen, Yudong
This paper gives an analytical proof of the conjecture given in [1]: when the dimension $M$ of the auto-covariance matrix is large, the eigenvalue spectrum from Principal Component Analysis (PCA) of...
Contour Extraction And Tracking Of Moving Vehicles For Traffic Monitoring (2008)
Zhimin Fan, Jie Zhou, Dashan Gao, Zhiheng Li
Abstract-- A robust algorithm is proposed in this paper for contour extraction and tracking of moving vehicles. A snake model is modified, in which directional information is utilized to guide the...
