基于不可分离小波框架变换的图像融合技术

以不可分离小波框架变换为依托,对两个传感器在同一时刻获取的同一场景的图像进行融合。首先,对各原图像进行不可分离小波框架变换（NWF）;然后,根据变换后系数计算图像的对比度量测,融合处理为基于对比度量测的系数选取过程,并对选取后的系数进行一致性校验;最后,对组合后的系数进行NWF逆变换,得到融合后的图像。

Image Fusion Technology Based on the Framework of Non-Separable Wavelet Transform

Based the non-separable wavelet frame transform, syncretize images of the same scene 2 sensors at the same time. First of all, for non-separable wavelet frame transform on the original image（ NWF）; then, according to the transform coefficient calculation contrast of image measurement, fusion processing process of selection coefficients based on comparative measurement, and consistency checking for coefficient selection after,finally, the inverse NWF transform coefficient of combination of, the fusion image is obtained.
