高动态范围图像及其色彩迁移

High dynamic range image and color transfer

高动态范围图像是一种可以大范围表示场景中亮度的变化,像素值正比于场景实际亮度的图像类型。对高动态范围图像以及普通图像间的色彩迁移进行了研究。先将图像变换到正交的色彩空间,然后根据图像的色彩信息统计值,将参考图像的色彩迁移至目标图像中,使生成的新图像具有参考图像的整体色彩特征。实验表明,色彩迁移效果满意。

High dynamic range image,whose pixel value is proportional to the true radiance,can represent a wide range of scene’s luminance.In this paper,the technique of color transfer is studied between high dynamic range images as well as general images.Firstly,puts both a reference image and a target image to an orthogonal color space,computes their color distributions.Then imposes color characteristics of reference image on target image to generate novel image.Experiments show that result of color transfer is satisfactory.
