AI中文摘要:

研究了偏微分方程(PDE)可视为由数据项和光滑项组成的能量泛函的欧拉-拉格朗日(E-L)方程的情况,给出了PDE成为对应泛函的E-L方程的必要条件。将该能量泛函应用于彩色图像去噪问题,结果表明该方法相比当前最先进的彩色图像去噪技术具有竞争力。

英文摘要:

The case when a partial differential equation (PDE) can be considered as an Euler-Lagrange (E-L) equation of an energy functional, consisting of a data term and a smoothness term is investigated. We show the necessary conditions for a PDE to be the E-L equation for a corresponding functional. This energy functional is applied to a color image denoising problem and it is shown that the method compares favorably to current state-of-the-art color image denoising techniques.
