The Edge image description paper claims that the system is "Scale-Invariant". On page two, it says that scale invariance is achieved by "normalizing the edge map to WxW pixels". In other words, if I present the same image at two resolutions, the system can normalize them to the same size. This is hardly scale-invariance. In fact, this only could work if you surmise that the object has been perfectly segmented (or at least provided with a cropping rectangle), but the authors claim that their system avoids "segmentation preprocessing" , but unless I am not understanding it correctly, it appears that every object IS provided with a segmentation by bounding box. There is no reference to a multi-scale global search e.g. Viola and Jones either.
Reading this, it appears that the authors are not up to date with the literature, and that many relevant references are missing.

This is in great contrast to the PAMI paper which is well-written and insightful.
