With linear YCBCR space and Reinhard’s statistical color transfer strategy

a color transfer method for image fusion

named YCBCR color transfer method

is proposed to produce a fused image with a natural daytime color appearance. This approach has low computational complexity

and is very suitable for color image fusion. Furthermore

it facilitates enhancing the luminance contrast of the color fused image by replacing the luminance component of the color fused image with the high-contrast grayscale fused image. The paper mathematically proves that color spaces conforming to the general YCBCR space framework

such as YUV space

can be used as an alternative to YCBCR space in color transfer. Experimental results demonstrate that YCBCR color transfer method is able to give color fused image a natural daytime color appearance

and has better capability of recoloring color fused image than Reinhard’s approach.
