The reviewers found that this paper provides excellent results for image segmentation, building off of previous work. There was some disagreement among the reviewers on a few areas. The first of these is novelty -- always a tricky subject -- where some reviewers noted that the work appears to be incremental methodologically. However, given that the results provide a novel contribution to the field, I think that this is not a particularly strong drawback. There were questions raised about the clarity of the paper. I believe that these have been reasonably addressed by the author response -- and I have also read the paper myself to judge clarity, and feel that it is acceptable. That said, I do expect the authors to fully incorporate the feedback from the reviewers to further improve the paper, as promised in their author response.
