The most widely used algorithms for classical feature detection today are "whatever opencv implements" In terms of tech that's advancing at the moment? ML techniques. https://co-tracker.github.io/ https://co-tracker.github.io/ if you want to track individual points, https://github.com/matterport/Mask_RCNN https://github.com/matterport/Mask_RCNN and its descendents if you want to detect, say, the cover of a book.
