> No one's going to start carrying cardboard patches around
Uhhhh... why not? You can put them on hats, backpacks, arm patches, or a lot of things. I get that they are suggesting it would be uncomfortable to have a stiff shirt, but there are easy solutions here.
I'm not trying to undermine the research here (because it is good research) but I think the reporting could be a little better.
As for the research, I wished they had compared it to more accurate models. I think this would greatly help a reader to understand the limitations of the work. YOLO and faster-RCNN are great for "real-time" but don't have the greatest accuracy. They trade accuracy for speed (more accurate models are pretty slow). While I do think YOLO is more similar to what would be used in a real life setting, it would be great to know how the design works for more accurate models (this wouldn't require significantly more work either, since you're just testing against pretrained models). If the researchers stumble across this comment I would love to know if you actually did this and what the results were (or if you see this comment and try it against a more accurate model). (I do also want to say to the researchers that I like this work and would love to see more)
