【摘要】 图像之间的颜色传输有效地利用了图像的基本统计信息.提出一种基于图像的简单统计信息和梯度域信息的局部颜色迁移算法,其中提供了简单易用的操作界面,在迁移过程中能够保持源图像的颜色细节;将其推广到灰度图上色问题,可有效地提高上色速度.实验结果表明,该算法较好地实现了源图像和目标图像的局部区域颜色对应,生成具有较好视觉效果的真实自然的新图像.更多还原

【Abstract】 Color transfer between images use the statistics information of images effectively.This paper presents the local color transfer approach based on the simple statistics and gradient domain information of images.Our approach proposes a sketching interface,can preserve the color details of source image,and can extend to colorization problem for improving the speed of colorization.Various experimental results show that our approach can specify the correspondences of local color regions in source and target images,and generate actual and natural results for visual effect.更多还原
