MR.Liu, you said in the article that "To further improve the quality of edges, we use image pyramids during testing" why did you choose the scale like "0.5 1 1.5 "

liu师兄你好,请问多尺度融合为什么要选择0.5 1 1.5这三个比例,我也发现加入升采样的比例后对边缘检测效果更好,但是对图片进行升采样后图片的细节丢失,为什么还会达到好的效果呢?

[0.5, 1, 1.5],小于原图、原图、大于原图,而且比较整,大于1.5的可能会影响速度。
