| 摘要： | Starting with an introduction to the wavelet theory and a comparison of Fourier based approach with the wavelet-based approach, we examine the issues involved in applying the wavelet-based compression to the transportation surveillance, the requirements for traffic surveillance, etc. Illustrations showing the effects of excessive compression are given. A discussion of the need for and implementation of the lens defogging mitigation and a discussion of bad weather effects are presented. The algorithms for image processing and the vision based vehicle tracking and counting are also presented. Finally the technical and market potential and the issues of further product development and implementation are also presented. |
