The imaging system is taken as a stable  linear  time-invariant  and causal filter  and its transfer function is measured through the pseudo-random binary sequence impulse responses identification. A digital mirror device (DMD) light projector is developed as the target generator  and wavelet thresholding is used to denoise the captured image. Pre-filtering spectral estimation algorithm with adaptive parameter selection is also proposed for the identification process  overcoming the challenge brought by the size limit derived from the optical isoplantic region. Simulations and experiments are presented to show the effectiveness of the proposed method.0-64. 2010 IEEE.   Research on Wavelet Denoising of AE Signal in Evolution Process of Coal and Gas Outburst 会议论文 2nd International Conference on Mine Hazards Prevention and Control, OCT 15-17, 2010 作者:  Yang Huiming;  Wen Guangcai;  Li Jiangong;  Sun Wenbin 收藏  |  浏览/下载：1/0  |  提交时间：2019/12/31 Acoustic Emission  Wavelet Analysis  Denoise  Time-Frequency Analysis
