This paper describes a novel image reconstruction method based on modified exemplar based technique. This modification allows to choose sub-optimally image-adaptive form and size of the block in order to find similar patches, number of which is further increased by rotation of these blocks. We show that the efficiency of image reconstruction depends on the choice of block size for the exemplar based method. Proposed block size selection adaptivity allows to obtain a smaller reconstruction error than that of the traditional method as well as other state-of-the-art image inpainting methods. We demonstrate the performance of a new approach via several examples, showing the effectiveness of the proposed algorithm in removal of small and large objects on the test images.
