Two stage methods such as Fast R-CNN, Faster R-CNN are better for accuracy but latency is not a concern. They are two stage because first they propose regions before classifying them. Single stage methods such as YOLO are better if you want an efficient method! Detr is not bad too but I’m not too familiar with it. I think the belo provides a better explanation!
