Abstract

To obtain ideal repair effects, an improved Criminisi algorithm-based image repair algorithm was proposed specific to the shortcomings of Criminisi algorithm which costs much repairing time, its feasibility and superiority were tested. First, priority calculation was improved to find optimal to-be-repaired block; then optimal matching block search strategy was improved to find optimal matching block; finally, new confidence update modes were adopted to obtain more ideal repair effects and the simulation experiment was made to test the algorithm performance. Results indicated that compared with Criminisi algorithm not only could obtain ideal image repair effects but also could sharply reduce repair time and improve image repair efficiency.
一种改进的基于犯罪算法的图像修复算法
为了获得理想的修复效果,针对Criminisi算法修复时间过长的缺点,提出了一种改进的基于Criminisi算法的图像修复算法,并对其可行性和优越性进行了检验。首先,改进优先级计算,找到最优待修块;然后改进最优匹配块搜索策略,找到最优匹配块;最后,采用新的置信度更新方式获得更理想的修复效果,并进行仿真实验验证算法性能。结果表明,与Criminisi算法相比,不仅可以获得理想的图像修复效果,而且可以大幅缩短修复时间,提高图像修复效率。
