Note on "Optimized JPEG Image Decompression with Super-Resolution Interpolation Using Multi-Order Total Variation"

After publishing this ICIP paper, we noticed that a very similar approach has already been proposed by the paper "Artifact-Free Decompression and Zooming of JPEG Compressed Images with Total Generalized Variation" in the proceedings of VISAPP2012 (as well as in Springer, Computer Vision, Images and Computer Graphics, CCIS).

We also note that the sentence in our paper "...this primal definition of TGV is first introduced by Setzer et al. in [11]." is somehow misleading, because the primal formulation also appeared in [10].

We apologize for any confusion this may have caused.

Thanks to Dr. Martin Holler for pointing out.
