θ解耦出去单独作为一个分类任务了,使用BCE作为损失函数,剩余四个参数作为另一个回归任务,因此使用水平框的CIoU作为回归loss。
置信度损失有两种选择,正样本全部置为1或者以IoU作为该置信度损失分支的权重,采用后者预测出来的置信度会降低但是整体精度会提升,这里采用的是后者。所以这里置信度损失的权重又有两种选择,一个是水平IoU,另一个是RIoU,后者明显更好,但是我写的RIoU的计算效率太低,虽然最后的精度会上升一点点但是运算时间增加了一倍,性价比不高,因此没有启用

我看算法默认的输入为1024*1024,这个尺寸是不是很大呢?需要什么设备才能训练起来呢?
谢谢

我应用在遥感检测领域所以尺寸比较大,你完全可以根据你自己的情况设置成你的数据集大小,具体什么设备得看你使用什么规模的模型以及batchsize的大小

maybe is your RIoU don't care all. ep: The Intersections and the endpoints coexist.
