The submission originally received scores mixed region that put it into the borderline region. The reviewers praised the simple and apparently effective method, but also noted a number of issues, in particular an unclear relation to [34] (which itself is rather unclear) as well as an insufficient experiment evaluation. In their response the authors provided additional information and results, which the reviewers appreciated. A detailed discussion followed, that ultimately let to the conclusion that the contribution is valuable and that authors should not be punished for a lack of clarity in the prior work [34]. Therefore, the recommendation is to accept the work. The authors are encourage to incorporate the reviewer suggestions and the material of the rebuttal into the camera-ready manuscript.
