The review scores were somewhat borderline, but overall slightly above the acceptance threshold. There was some disagreement among the reviewers, following which a discussion was initiated. The rebuttal largely addresses the concerns of R1 (the most negative review), and in the metareviewer's opinion does a reasonable job of addressing these concerns, which are mostly clarifications regarding the performance of the algorithm. Positively, the reviewers mostly concur that the method, while fairly straightforward, offers significant improvements over existing techniques. After discussion there was some positive movement in review scores resulting in a positive consensus among reviewers.
