There have been many better feature detectors introduced in the mix over the past fifteen years. This change won't make too big a difference for people in the CV community.
- Rochetshipz 7y agoMhhhhh, I'm a researcher in the field and I'd say it's a mostly inaccurate statement. The root-SIFT detectors and descriptors are still really good. If you try to match images in different conditions (day/night), then CNN based approaches are OK. Which one were you thinking about?
- johntiger1 7y agoI would argue more that SIFT was valuable in introducing a new paradigm of feature extraction/matching. It is a staple of many computer vision courses. But yes the main algorithm I'm sure is quite (practically) performant as well
- FRIEDCHICKEN 7y agoGMS feature matching trumps SIFT (and all other feature matchers) in just about every category including performance.
