摘要
分析图像彩色化的病态性,按照解决病态问题的规整化形式将彩色化分为基于颜色转移和利用颜色扩展的两类方法。颜色扩展彩色化方法的核心在于对颜色扩展过程的合理控制,分析比较了基于总体控制和局部控制的两类颜色扩展方法,探讨了不同控制形式之间的关系、对初始涂色的设置要求及颜色模型的选择问题。可操作性和有效性是此类方法的优势,进一步改善处理效果的真实性并增强处理纹理图像的能力,有望发展成为真正实用的彩色化技术。
Colorization is treated as an ill-posed problem. Colorization methods are divided into two kinds according to their regularization forms: the one on the basis of color transfer and the other one by using color propagation. The core problem in color propagation based methods is the reasonable control of the color propagating process. This paper analyzes and compares the macro-control and local-control propagating methods. Then the relationship between different controlling initial color scribbles and the selection of color modal in colorization are feasibility are significant advantages of such colorization methods using colorized results more realistic and enhance the applicability for texture technique may be created based on such methods. modes, the requirements for the discussed. High operability and color propagation. To make the image, the practical colorization
