Distribution-Aware Image Color Transfer

1 Introduction

Color transfer is a practical image editing technology which is useful

in various applications. An ideal color transfer algorithm should

keep the scene in the source image and apply the color styles of

the reference image. All the dominant color styles of the reference

image should be presented in the result especially when there are

similar contents in the source and reference images.

Reinhard et al. [2001] present a global color transfer algorithm

which manipulates the pixel value of source image to match the

global mean and standard deviation of the reference image in a

uncorrelated color space l. Unnatural results may be produced

when the color distributions of source and reference images are very

different. Dong et al. [2010] extract the same number of dominant

color descriptor (DCD) from the input images and find an optimal

one-to-one mapping between the dominant color sets. All the obvious

color styles of the reference image can be presented in the

result if there are enough corresponding dominant color patterns

in the source. However, as shown in Figure 1, the normal local

color transfer algorithms will fail to generate a satisfied result if

the number of source dominant colors is much less than the reference

one, especially when the color styles are transferred between

similar contents. Moreover, the spatial distribution of the reference

color pattern should also be considered during the transfer process.

We propose a robust color transfer framework to address the above

issues. Our method can establish a soft connections between the

local color statistics of the source and reference images. All the

obvious color features can be presented in the result image, as well

as the spatial distribution of the reference color pattern.
