为了在一定的区域内融合多幅光学图像的信息，采用了一种基于联合图像专家小组（ JPEG）图像压缩编码的小波域多幅图像融合算法。其基本思想是将小波逆变换看作是信息的融合过程，先对多幅图像进行JPEG压缩编码，压缩后得到一组二进制码流，这组二进制码流可以直接作为小波变换的分解系数，经小波逆变换后得到融合信息。结果表明，该算法能够实现多幅灰度图像和彩色图像的融合，提高了单一空间内图像的信息量，有利于多图像的存储和传输。

In order to fuse the information of multiple optical images in a certain area , an image fusion algorithm based on joint photographic experts group ( JPEG ) in wavelet domain was adopted .The main idea of the method was to regard the inverse wavelet transform as information fusion process .Each source image was compressed into a group of binary code flow according to JPEG standard .Then the group of binary code flow was taken as the wavelet coefficients and the fused image was obtained by taking inverse wavelet transform .The results show that the algorithm can realize the fusion of multiple gray-scale images and color images , improve the amount of information in a single space and be conducive to multiple images storage and transmission .
