Two developed color image fusion techniques, the MIT scheme and the TNO scheme, are applied to visible and infrared images. They are enhancement and nonlinear methods. This paper provides a discussion of the linear fusion scheme once again. At least two conclusions can be testified by the fusion experiment on two sensor images in this paper: one is the linear fusion scheme has good performance in some images modalities; the other is the linear fusion has better performance in the fused color space YUV than in the RGB. A key problem of the linear fusion, how to assign or weight sensor images to three channels of a color space, was studied with the correlation between dual-sensor images, and experimental results show that the assignment or weight is related with the correlation between sensor images. But this study is mainly for the Y channel in the interest of preserving the details from both of two sensor images, and the relationship between the assignment or weight of a linear fusion and the correlation between sensor images need to be studies further in future.
