On the contrary, when the defect in the image is small compared to the patch size, it is possible that the algorithm recovers the structure with just one iteration as is shown in Figure 14. This is also possible, when the initial inpainting function u0 is already close to solution in the sense, that any point in the inpainting domain has enough reliable information within the patch around it.
The patch size also heavily influences the ability of exemplar-based inpainting methods to recover structures. To grasp this issue, we consider an example on a synthetic image and show, that the patch size should not be chosen too small in comparison tothe texture. The problem, which can occur when the patch size is chosen too small, is that a repetitive ...
