Paper Abstract

A color transfer method is presented to give fused multiband nighttime imagery a natural daytime color appearance in a simple and efficient way. Instead of using the traditional nonlinear lαβ space, the proposed method transfers the color distribution of the target image (daylight color image) to the source image (fused multiband nighttime imagery) in the linear YCBCR color space. The YCBCR transformation is simpler and more suitable for image fusion compared to the lαβ conversion. The YCBCR transformation can be extended into a general formalism. And the paper mathematically proves that, for color transfer, using color spaces conforming to this general YCBCR space framework can produce same recoloring results as using the YCBCR space. Experimental results demonstrate that the YCBCR based color transfer method works surprisingly well for transferring natural color characteristics of daylight color images to false color fused multiband nighttime imagery, and moreover, can also be successfully applied to recoloring a variety of color images.
