是基于变分的方法，此类方法将图像处理领域的

问题用变分方法转化为某个泛函式的最小化问题，

最具代表性的变分去噪模型是总变差( Total Variation，

TV) 模型即TV 模型-Is based on the variational method, such methods to problems in image processing by variational methods into a pan function minimization problem, the most representative model of variational denoising total variation (Total Variation, TV) model that is TV model
