| Summary: | 碩士 === 逢甲大學 === 資訊工程學系 === 103 === Renovating for a large-scale image smudge is seldom considered in the preservation of classical archives. It is due the fact that the we just have little reference information for repairing the target area. Thus, it is hard to obtain satisfactory renovating performance. To conquer this problem, we apply advanced SSD calculation and edge confidence to design an exemplar-based repairing mechanism. The adoption of advanced SSD is expedient in looking for a close reference patch, while that of edge confidence is useful for avoiding the phenomenon of error diffusion. Specifically, a semi-fragile watermark is embedded into the target area simultaneously in the process of renovating, which can be used to preserve the copyright of improver. The experimental results have demonstrated that these reformations can help in renovating a large-scale smudge in digital image archives and provide copyright protection in delivering the repaired image over the Internet.
