WebMay 10, 2024 · In the post-processing phase of RetinaNet, the classification score of each predict bounding box is directly used to feed into the non-maximal suppression (NMS) procedure. Under this regime, the prediction boxes with higher classification scores will be retained, while the nearly lower ones will be discarded. WebNov 22, 2024 · The models were then used to detect difficult samples and we compared the results. Results: The mean average precision (MAP) of RetinaNet reached 82.89%, but the frames per second (FPS) is only one third of YOLO v3, which makes it difficult to achieve real-time performance. SSD does not perform as well on the indicators of MAP and FPS. rock cycle tutorial learner.com
