Abstract: Criminisi has proposed an exemplar block-based image inpainting algorithm. In this paper, the priority computation formula is improved by leading an [α] factor, in order to make the algorithm more sensitive to the detail of image texture during the inpainting procedure. In the priority computation formula, the addition is used instead of multiplication to prevent rapid decay, it can enhance the inpainting effects. Experimental results show that the proposed algorithm can be satisfied by the inpainting effects.

摘要： Criminisi等人曾提出一种基于样本块的图像修复算法，将其算法中优先权的确定进行了改进，通过引入调节因子[α]调整填充边缘优先级顺序，使算法在修复过程中对图像纹理细节的部分较为敏感；同时将优先权公式由相乘改成相加，防止快速衰减，提高修复效果，并从实验证明了算法的有效性。
