没有,这个改动太小了。如果能把样本匹配方式改成适合高斯分布的方式的话,那样还不错。

大佬,你说的样本匹配方式是指哪一块呢?

大佬,你说的样本匹配方式是指哪一块呢?

yolov5的样本匹配代码实现在loss.py->Class ComputeLoss->def build_targets,选取距离GT中心点最近的3个cell的anchor,计算anchor与GT的高宽比例,比较阈值实现正负样本分配。现在bbox表示改成高斯分布,只修改损失函数的计算,改动不多,提升也并不是很大。 或许这篇论文可以帮助到你。General Gaussian Heatmap Label Assignment for Arbitrary-Oriented Object Detection
