同时采用对偶方法来避免全变分项的非光滑性和高非线性性。
The algorithm also adopts dual method to avoid the nonsmooth and highly nonlinearity of total variation term.
最后讨论了利用全变分方程建立有限元的方法。
Finally, based on the total variational equation, the finite element method of these problems is also discussed.
基于全变分的彩色图像修复(CTV)模型,可以在保持边缘的同时达到去噪目的,但对纹理较复杂的区域修复效果不理想。
The Color Total Variation (CTV) model can denoise while maintaining the edge of the damaged images, but it should be improved in domains of complicated texture.
