彩色图像间的颜色迁移在图像处理和数字娱乐领域具有重要应用。为增加颜色迁移效果的多样性,研究了颜色迁移的本质,并在 Reinhard 算法的基础上,提出了基于放缩系数和均值的多参数颜色迁移方法,不仅对放缩系数给出了多种选取方式,而且将原来单一的参考图像的均值改为原图像均值和参考图像均值按一定比例搭配的数值,最终使得原图像经过颜色迁移后可生成多种结果图像,以供用户根据不同的喜好选择不同的视觉效果。然后将其推广到多幅图像之间的颜色类比问题。最后通过若干实例验证了本文方法的有效性。

Color transfer between colorful images has important applications in the area of image processing and digital edutainment.In this paper,the essence of color transfer is investigated based on Reinhard's method,a new method for color transfer with multi-parameters is proposed by combining the scaling and mean values.Various choice of scaling values is presented and the mean value of the reference image is changed into a value as a linear combination of mean values of reference image and source images.By the proposed method,various different colorful images with different visual results can be obtained from given images,which provide more choices for users.Then the proposed method is extended to color analogy between multiple colorful images.Several examples are presented to show the effectiveness of the proposed methods.
