您好,我有两个问题,
1.第三层网络输出的10个点,前5个是x 后5个是y 的偏移比例对吧?
2.在pad中box是有微调的,total_boxes是否也应该调整一样?
谢谢

Title: Questions in Matlab Code

Hi there, I have two questions,

  1. The third layer of network output 10 points, the top 5 is the y after 5 is the offset ratio of right?
  2. In the pad box is fine-tuning, total_boxes should also be adjusted?
    Thank you

  1. 对的,bounding box内相对位置
  2. pad不是调整box,只是计算一下哪些box越界到图像外,越界了多少,方便后面crop patch时候在越界地方补0。

@kpzhang93 谢谢您的工作!我有两个关于pad的问题想请教您:

  • 请问pad操作后的tmpim变量可以初始化为127.5吗?因为我看后边会把它缩放到以[-1, 1],而现在的zeros相当于直接填充了黑色,不知道灰色会不会好些呢?
  • first stage得到的total_boxes后,现在是先做了一次类似bbreg的操作才传给pad,而second到third的时候就直接调用bbreg了,我能找到的区别只有“前者的bbwbbhbbreg 里的w和h 要小1”,请问这个区别是有益的吗?是不是first stage模型训练的时候就是这么训练的,导致不适合再加1了呢?
