Thank you for sharing. To continue this thread, I’d like to share my baseline for this competition too. Which is mainly inspired by planet notebook from lesson 3.
My way was to simply combine 3 1-channel images (discarding yellow images) to 1 RGB 3-channel image with greate tool imagemagick https://www.imagemagick.org/script/index.php
Combining images would be as simple as this command in linux shell:
convert r.jpg g.jpg b.jpg -channel RGB -combine combined.jpg
So workflow would assume you have a combined images in your train and test folders.
This notebook would not get you on top of LB, but provide a nice and simple way to start playing with data and experimenting further.
And here is a link for Kaggle discussion topic.
Tnanks to fastai team and community.
