Abstract: An image fusion scheme based on the wavelet transform and an image compression algorithm based on zero-tree coding are proposed, aiming at the demand of the Intelligent Transportation System(ITS). The algorithm is used to fuse visible image and infrared image with wavelet transform and then to compress the fused image by fully employing the importance degree of the subband coefficients and visual characteristic of mankind. So it enhances the integrality and oneness of the traffic information availably and also improves the quality of the system greatly.

Key words: image fusion, wavelet transform, zero-tree coding, Intelligent Transportation System(ITS)
