基于框式约束的图像着色快速算法

Fast image colorization algorithm based on frame constraint

通过增加控制函数,结合Le去噪模型的保真项,提出了一种新的图像着色模型。利用交替方向乘子法对该模型进行了快速求解。实验结果表明,该模型不仅能有效地防止图像着色过程中颜色的越界,还能保证图像着色的质量。

A new image coloring model is proposed by adding control functions and combining fidelity term of Le denoising model. The model can be quickly solved by using the alternating direction multiplier method. Experimental results show that the model can effectively prevent the cross boundary in the process of image coloring and guarantee quality of the image coloring.
