中文摘要：

在BSCB模型上考虑了图像的梯度以及相应邻点的信息,引入m ax/m in函数,提出用ASG算子代替光滑算子,对BSCB模型进行修改.实验证明,新算法能较好地对图像进行修补,尤其是在保持边缘和角点的特征上效果比较好.

英文摘要：

A new ASG operator is proposed by employing partial neighbouring points by max/min function,not considering all the neighbouring grey values,and is used as an appropriate information propagating estimator to modify the BSCB model.The modified image inpainting model proved by experiments to be able to get good results at the edges and corners.
