10.5 Experimental Results 215

Figure 10.10 Comparisons of different structure propagation approaches, zoomed-in partitions.

From left to right: removed blocks (black blocks) with assistant edge information; inpainting result

by PDE-diffusion [225]; inpainting result by patch-wise synthesis [217]; inpainting result by our

scheme. Note that only our scheme takes advantage of the edges.

Table 10.2 Percentage of different coded elements in our JPEG-based system (QP is set to 75).
