Probabilistic two-stage detection
Webb20 nov. 2024 · A second-stage detection head is run on aligned features [ 10, 28] of each proposal. Some systems use single-stage detectors [ 22, 24, 25, 26, 41, 43 ], which does not have RPN and directly predict object categories and regression offsets at … Webb8 juni 2024 · Probabilistic interpretation of two-stage detection 기존의 two-stage 모델은 RPN이 객체=1, 배경=0 정보를 담은 region proposals를 생성합니다. 또한 head는 객체=1인 경우에만 분류를 진행했습니다. 즉, RPN에서 P (O)를 예측하고, second-stage에서 P (ClO)를 예측했었습니다. 해당 논문에서는 두 확률을 하나로 묶습니다.
