Thank you for keeping us old school computer vision guys in buisness. If deep learning folks actually used good calibration, and didnt constantly argue eh an offset of a few pixels does not matter, they might actually be competetive with classic methods by now. Well competetive accuracy wise, but not performance wise at least. Most VO systems localize a camera before the images have been uploaded from ram to the gpu, and deep learning will have a hard time getting around that kind of performance limit.
