摘要 证明一类非线性抛物方程ut-g(DGσ*u,D2Gσ*u)Du div DDuu=0u(x,0)=u0粘性解的存在惟一性,并通过实验验证了该模型在图像处理中的应用. This paper proves the existence and uniqueness of the viscosity solution of the following equation:{ u/ t-g(DGσ*u,D^2σ*u)|Du|div(Du/|Du|)=0 u(x,0=u0)The paper also indicates some applications of this model in image processing and edge detection.
