Reviews: CRF-CNN: Modeling Structured Information in Human Pose Estimation

The general idea of this work is clearly in a direction of interest to the community and the results look strong. However, there are a few aspects to this work that I find quite unclear. If they were clearer this work would have much more potential for impact. In particular, it is not clear enough if this work uses a truly'end-to-end' approach (as stated for one of the contributions). For example on line 46 it is stated that: "We show step by step how approximations are made to use an end-to-end learning CNN for implementing such CRF model."
