| 摘 要： | 针对五台山壁画破损区域形状不规则、大小不均匀,采用Criminisi算法修复时易出现错误填充的问题,提出一种改进的块匹配五台山壁画数字化修复算法.首先在计算优先权,除置信度与数据项之外引入分散度项,确保信息最丰富的块被优先修复;然后结合图像块结构的整体性将协方差因子引入相似度计算中,以减少错误填充率.对五台山破损壁画进行数字化修复的实验结果表明,该算法较好地解决了Criminisi算法的错误填充问题.

| Abstract: | In order to avoid the error filling problem caused by irregular shape and uneven size of damaged areas in Wutai Mountain murals,a novel block matching algorithm was proposed.First,a dispersion item was introduced in the priority calculation process except for a confidence coefficient and a data item originally,which might guarantee that the most informative block would be inpainted primarily.Then,the covariance factor denoting structural integrity among image blocks was adopted in similarity calculation to reduce error filling rate.Experimental results on Wutai Mountain murals illustrate that the proposed algorithm can solve the error filling problem of the original Criminisi algorithm effectively. |
