For The Continuous Method, The Tv Image Restoration

The paper presents a class of important processing technology of image processing: image restoration, or image reconstruction, or image recovery, which is very early in development and very wide in application. At the same time, it summarizes briefly some primal content about optimization method. The paper emphasizes to tell of the problem about using TV model to deal with image processing. To solve TV-based image restoration problem also can be looked upon an optimization problem, namely, to solve corresponding Euler-Lagrange equation. There are many ways to solve nonlinear elliptic Euler-Lagrange equation, and we emphasize to tell of combining classical Newton method and continuation method to deal with equation.
