Improved exemplar-based algorithm for image inpainting
Fang Baolon · Computer Engineering and Applications Journal · 2014
In order to solve the problem of inaccurate filling orders in Criminisi algorithm, an exemplar-based algorithm for image inpainting is proposed. Color variation between neighbor pixels is used to define the priority function and image structures propagate firstly. Besides, quality of exemplar filling is introduced into the update of confidence term. Confidence value is relatively high when the difference between the target patch and the similar patch is small. In addition, the patch that with minimum gradient distance is adopted when there are several most similar blocks with a same color distance. Experimental results show that the improved algorithm achieves high inpainting quality on various kinds of images.
