基于图像修补技术的污点自动侦测及去除方法

摘要

In view that digital camera is capable of constantly taking pictures under the same dust-stain condi-tions, this paper proposes a method of automatic stain spot detection and removal based on image inpainting tech-nique.Experiments indicate that this method can effectively remove stain spots of digital images, the restoration re-sults are optimal, and the algorithm can effectively solve the issue of CCD contamination of DSLR camera.%利用相机可以在相同污染条件下反复拍摄的特点，本文提出一种根据参考照片来自动侦测照片中的污点并利用图像修补技术将污点去除的算法。实验表明，该方法能够在不丢失原始图像信息的情况下有效地去除数字照片中的污点，复原效果良好，该算法能够有效地解决单反相机感光元件污染的问题。
