By test in low contrast image  2D continues Gabor wavelets are adopted to realize feature extraction. By optimize Gabor wavelet's parameters of translation  the feasibility and effectiveness of the algorithm are demonstrated by VC++ simulation platform in experiments. 2004 IEEE.  orientation  and scale to make it approximates a local image contour region. The method of Sobel edge detection is used to get the initial position and orientation value of optimization in order to improve the convergence speed. In the wavelet characteristic space  we adopt PSO (particle swarm optimization) Algorithm to identify points on the security border of the system. Comparing to the LM algorithm  it can ensure reliable convergence the target  which can improve convergent speed   Intelligence and Security Informatics for Homeland Security: Information, Communication, and Transportation 期刊论文  OAI收割 IEEE Transactions on Intelligent Transportation Systems, 2004, 卷号: 5, 期号: 4, 页码: 329-341 作者:  Hsinchun Chen;  Fei-Yue Wang;  Daniel Zeng 收藏  |  浏览/下载：29/0  |  提交时间：2017/05/17 Border and transportation security, homeland security, infectious disease informatics, intelligence and security informatics.
