Image reconstruction by modified exemplar based inpainting

Exemplar based image inpainting technique is one of the inpainting techniques which uses self similarity priors. The main aim is to fill damaged area of image by copying patches from remaining image. Patch priority, governed by confidence term and data term, decides the order in which filling should occur. This paper proposes the calculation of data term by using edge map technique rather than isophotes directions. The proposed paper gives the comparison of different distance metrics such as sum of squared distance, Hamming distance and normalized cross correlation used to find best matching patch.
