Dear @AlexeyAB ,
Thank you very much for your help.
However, yolov3-spp.cfg uses 5x5 9x9 13x13 in SPP, while in the article 5x5 7x7 13x13: 'DC-SPP-
YOLO_ Dense Connection and Spatial Pyramid Pooling Based YOLO for Object Detection'
why you choose 9x9 instead of 7x7 ? Is there any theory support or mathematic support?
Looking forward to hearing from you, thanks a lot.
Best regards, May
This was chosen by Joseph. I don't know why, may be to increase receptieve field, may be he tested both approaches, but may be just a typo )
Dear @AlexeyAB ,
Sorry for bothering you.
When I compare the Yolov3.cfg and Yolov3-spp.cfg, I find that you use spp structure to replace the 78 layer of Yolov3.cfg for creating Yolov3-spp.cfg. i.e., you use spp structure to replace a 3*3 conv layer in Yolov3.cfg.
I'd like to know why you use spp structure to replace the 78 layer? why you did't replace any other layer? Is there any theory support?
Looking froward to hearing from you, thanks in advance.
Best regards, May
