Image Inpainting Methods Evaluation and Improvement

الملخص EN

With the upgrowing of digital processing of images and film archiving, the need for assisted or unsupervised restoration required the development of a series of methods and techniques.

Among them, image inpainting is maybe the most impressive and useful.

Based on partial derivative equations or texture synthesis, many other hybrid techniques have been proposed recently.

The need for an analytical comparison, beside the visual one, urged us to perform the studies shown in the present paper.

Starting with an overview of the domain, an evaluation of the five methods was performed using a common benchmark and measuring the PSNR.

Conclusions regarding the performance of the investigated algorithms have been presented, categorizing them in function of the restored image structure.

Based on these experiments, we have proposed an adaptation of Oliveira’s and Hadhoud’s algorithms, which are performing well on images with natural defects.
