论述了基于小波变换进行图像融合的有关问题,提出了小波基选取的方法,推导了对小波滤波器组进行相位校正的原理和公式;接着,提出了一种新的高频通道的融合规则,并进行了实验.实验结果表明,提出的算法和融合规则对于不同源的图像,尤其是多光谱图像的融合,具有很强的实用性.

Some subjects of image fusion based on wavelet transform are discussed. Firstly, the method of selecting wavelet bases in image fusion is proposed, and the principle and formula on phase adjustment are deduced. Secondly, a new fusion rule of high frequency channel is presented. Based on the rule, a series of experiments are made on PC. The experimental result indicates that the algorithm and fusion rule are very suitable for multi-resource image fusion, especially for multi-spectral image fusion.
