This paper introduces image repairing model based on improved total variation.And the difference of gradient in image region will bring about different influence on image repairing.This text considers the influence of human vision psychology on image effect.A new variation function is proposed and the Euler-Lagrange equation of the model is put forward.This model proposed by this text is applied to a still image,and the contrast on image restoration effect is made.Still image repairing model is applied to v...
