摘要: 图像克隆一直是图像编辑中的重要组成部分,概括来说有基于透明度分量的、基于梯度域的、基于坐标的3种图像克隆方法,但图像克隆领域中存在的颜色不协调和边界失真问题一直没有得到很好的解决。为了缓解基于均值坐标克隆方法中的颜色不协调问题,提出一种基于局部亲和力传播的图像克隆方法,亲和力综合考虑了像素点与边界的坐标距离、颜色距离以及该点颜色在边界颜色分布中的概率,以此来缓解失色,达到颜色协调。亲和力还可以检测出真正感兴趣对象的边界,用它来约束边界插值,可以有效缓解边界失真,使得克隆更加鲁棒,最后的实验结果表明该方法能得到令人满意的结果。

Abstract: Image cloning has always been an important part of image editing. In general, it can be divided into three methods, based on a component, based on gradient domain, and based on coordinate respectively, but the color discordant and boundary distortion problems have not been well solved. In order to solve the color discordant problem in the method based on mean value coordinate, a method of image cloning was proposed based on local affinity propagation. The affinity considered the location information of pixels, color information, background information comprehensively, thus it could ease the color discordant and reach color harmonization. The affinity function could detect the real boundary of the interested object, which was used to constrain the interpolation on boundary, thus effectively ease the boundary distortion, and make the cloning more robust. The experimental results show that this method can get satisfactory results.

Key words: color harmonization, affinity, robust, image cloning
