@eragonruan hi, thanks for your link, it's very helpful. I try to modify ''ANCHOR_SCALES'' to [2,4,8,16], but I find "generate_anchors" function in "generateanchors.py" still generate 10 anchors not 80 anchors. This makes me very confused. I hope you can help me to understand.Thanks.^^

This 10 anchors' shape are "[(11, 16), (16, 16), (23, 16), (33, 16), (48, 16), (68, 16), (97, 16), (139, 16), (198, 16), (283, 16)]"

@Xiangyaojun anchor width is fixed to 16 according to the algorithm.(in conv5_3, each pixel in the feature map represents a 16x16 area of the original image). However, the height of the anchor is modifiable.
