适于图像融合的快速颜色传递方法

为获得具有自然日光色彩效果的融合图像，利用线性YCBCR空间和Reinhard统计颜色传递策略，提出了一种适于图像融合的颜色传递方法：YCBCR颜色传递方法。此方法不仅计算复杂度低，而且非常适合彩色图像融合，使得利用高对比度灰度融合图像替换彩色融合图像亮度分量，从而增强彩色融合图像亮度对比度的操作变得简单易行。本文从数学上证明了YUV等符合通用YCBCR空间模型的颜色空间用于颜色传递所产生的重染色结果，与用YCBCR空间得到的结果相同。实验结果表明，YCBCR颜色传递方法可以赋予彩色融合图像一种自然的日光色彩效果，其重染色彩色融合图像的能力好于Reinhard方法。

Fast color transfer method for image fusion

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.Th...
