| 摘 要： | 基于离敞小波变换的图像融合算法在特征表达上存在不足,将双树复小波变换引入到彩色图像融合中,对彩色图像的3通道分别进行融合,各通道低频取加权平均,高频去较大值的方法.融合效果评价除了使用均方根误差、峰值信噪比和熵外,还使用了通用的主观与客观相结合的方法.实验结果表明,获得的融合图像效果较好,优于离散小波融合算法.

| Abstract: | Since the deficiencies of the algorithm based on the existing discrete wavelet transform in the characteristics representation the Double-tree complex wavelet transform is introduced into the color image fusion.Three channels of the source color images are fused respectively.The weighted average is applied to the low frequency bands and the greater is applied to the high frequency bands.The performance evaluation methods of the RMSE,PMSE and universal measures combining the objective and subjective factors ... |
