关于回归的变量离散化选择 #50

target 被缩放过了,stride就是用来做这个的 LD/mmdet/models/dense_heads/gfl_head.py Line 246 in 2dda5c0

您好,感谢您的很棒的工作。我想将LD用到其他检测器中,关于把regression换成离散化的概率这部分有一个疑惑想要问问作者。我看检测器每一个scale得到的regression都通过相同的
integral
将概率转化成lrtb值,那么得到的lrtb都是一样的。所以最终不同feature scale的lrtb范围都是相同的,为什么不把每个scale的lrtb按照比例放缩范围呢?以及如果feature比较大,这样的实现得到的lrtb范围是否有可能小于GT lrtb的范围呢?LD/mmdet/models/dense_heads/ld_head.py
