YOLOv5 uses ICCV2023 snake convolution DSConv
[Remind everyone: The module has only been briefly packaged and tested. Everyone’s data is different. Whether it can increase the point requires more experiments. You can try different positions or make further improvements] DSConv is a fusion topology-controlled convolution proposed in ICCV2023 inspired by deformed convolution. It is mainly aimed at segmenting elongated morphological targets […]
