I see a flag. I like flags. Especially the Japanese flags. I don’t specifically care for Japan, but the flag is one of my favourites. I prefer flags with low entropy: so I wrote a script once that ranks the nations flags by entropy so I could quantify my preference. Thanks for letting me infodump a bit.
Their previous version was indeed without the coat of arms. Much cooler I think. During that time the Liechtenstein flag was identical, but they (Liechtenstein) changed it upon discovery.
I love that you have multiple people replying to you asking for technical details on how you ranked the flag entropy. This is how you know that you are amongst your people here <3
i’d define it as size of an svg file that represents the flag, since more complex flag -> more fundamental elements (rectangles, circles) needed -> bigger file size -> more entropy.
I tried different definitions and settled on spectral entropy. This one uses fourier transform and (I think) this takes the spacial relation of the pixels into account, as opposed to the more common Shannon definition. I’d like to share it but am not sure on how to do that: were I to use GitHub I would doxx myself.

I also love flags, flags are so beautiful (except the flag of Haiti, fuck you Haiti with your MS paint looking flag)

Well you gotta share that ranking now…
I owe it to the community. Since I don’t have it anymore I am coding it up again. Allow me some time - it’s weekend and I have family to look after.
And that script. I’m curious how you implemented it.
What is it about the flag of Japan that you like so much?
Simplicity I suppose. Colour combination. In my opinion if i can draw it from memory it’s a good flag.
Two colors, with a basic shape centered? I guess it’s ok.
How are you defining the entropy of a flag?
i’d define it as size of an svg file that represents the flag, since more complex flag -> more fundamental elements (rectangles, circles) needed -> bigger file size -> more entropy.
Subtracting it’s normalized negentropy from 1
How do you rate entropy? Is the script open source so we can see it?

…and what is the stack ranked result?
“Welcome to fun with flags!”
