Darknet - stuff to investigate

Things to investigate considering the darknet framework

Possibility of actually freezing the layers. This can be done by editing the last layer in the *.cfg file and adding the following parameter l.stopbackward = option_find_int_quiet(options, "stopbackward", 0);.

Improving YOLO for close together objects

Merge darknet upstream changes into a single commit

This can be done with the following commands

git pull --squash origin_PJREDDIE master
git add --all
git commit -m "Merge upstream PJReddie fixes"
git push -f https://gitlab.com/EAVISE/darknet.git master

Of course, if during the pull merge conflicts appear, you need to solve those first.
