摘要
在基于纹理合成的数字图像修复算法中,通常需要在已知区域搜索污损点所对应的匹配点,所选择的搜索匹配点的方法不同,会得到完全不同的修复结果 .先修复的污损点一旦获取了估计值之后,也会成为修复其余污损点的一个参考依据,因此所采取的修复顺序对修复过程的影响也是至关重要的.本文分别讨论了不同的搜索匹配点的方法和不同的修复顺序对修复结果的影响,并据此对污损图像进行合理和有效地修复.
In the digital image inpainting algorithms based on texture synthesis,the matching point of the damaged point is needed to be searched out from the known area.Totally different inpainting results would be obtained from different searching methods.Once one damaged point has been estimated,it can be used as the reference for the others.So the inpainting order is vital to the inpainting process.Influence on the inpainting results from different searching methods for matching point and inpainting order is discussed respectively.On the basis,the damaged image gets effectively restored.
