WebYOLOX is a single-stage object detector that makes several modifications to YOLOv3 with a DarkNet53 backbone. Specifically, YOLO’s head is replaced with a decoupled one. For each level of FPN feature, we first adopt a 1 × 1 conv layer to reduce the feature channel to 256 and then add two parallel branches with two 3 × 3 conv layers each for classification and … Web1.anchor-free 2.主干网络CSPDarknet和Focus 3.Decoupled Head解耦头 4.SimOTA. 1.主干网络CSPDarknet. yolov3中使用的是Darknet53，CSPDarknet是在其基础上，借鉴CSPNet的经验，产生的Backbone结构，而在yolox中的CSPDarknet也使用了Focus网络。 1.1Focus
