3-D整体变分视频去隔行方法

Video De-interlacing Based on 3-D Total Variation Method

提出了一种基于3D整体变分模型的视频去隔行方法。首先根据整体变分修复模型,建立3D灰度空间的光滑性能量函数,形成对隔行区域插值的约束;然后利用变分法将最小化能量函数的问题,转化为对Euler-La-grange方程的求解;最后根据隔行视频的特性,给出了一种非迭代的离散实现方法。实验结果表明,和常见的几种去隔行方法相比,本文方法能够较好地抑制边沿锯齿和运动虚像。

A video de-interlacing approach based on the 3-D total variation is presented.Firstly,a smoothness energy function in the 3-D gray field and a constraint of interpolation are established according to the total variation inpainting model.Then,the problem of minimizing the energy function is transformed into solving an Euler-Lagrange equations.Finally,a discrete non-iterative method is proposed.Experimental results show that compared with several common de-interlacing methods,the method can suppress the serrated edges and the virtual image.
