Model structure diagram of improved YOLOv5. We utilize C3-light to replace the C3 module and introduce the SimAM module into the neck layer of the baseline. PConv is partial convolution; SPPF is spatial pyramid pooling layer; SimAM is parameter-free attention coordinate mechanism; Concat is feature splicing layer, the feature map fusion operation; and Upsample is the up-sampling operation.
