  Well you gotta share that ranking now…

  • ByteJunk@lemmy.world ⁨2⁩ ⁨days⁩ ago

    And that script. I’m curious how you implemented it.

    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.

  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

  How are you defining the entropy of a flag?

  • ArmoredThirteen@lemmy.zip ⁨2⁩ ⁨days⁩ ago

    Subtracting it’s normalized negentropy from 1

    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.

  How do you rate entropy? Is the script open source so we can see it?

  source

  • residentoflaniakea@discuss.tchncs.de ⁨1⁩ ⁨day⁩ ago

    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 see, thank you that’s interessing; There is gitlab as github alternative but i think that making another account is just better then. Another solution is making here a spoiler with the code in it

  …and what is the stack ranked result?

  source

  • residentoflaniakea@discuss.tchncs.de ⁨1⁩ ⁨day⁩ ago

    That really depends on the algorithm used. Ideally it takes colous and spacial information into account. I’ll keep you posted on the ranking.

  I like Kazakhstan’s flag because I think its a nice combination of colors:

  Its not very low entropy though, at least not compared to ones like Germany’s or Ukraine’s.

  Hmm. It seems weird that any tricolour flags would have different entropies, but I don’t know how you would otherwise do a multichannel entropy.

  I was imagining a kolmogorov-esque doodad

  • residentoflaniakea@discuss.tchncs.de ⁨1⁩ ⁨day⁩ ago

    Yes! And weirder that bicolour banded flags are not consistently on top. I suspect some float errors. I just know that using the typical Shannon style does even worse. I might add some filter that calculates a differential or something.

  What is it about the flag of Japan that you like so much?

  source

  • residentoflaniakea@discuss.tchncs.de ⁨1⁩ ⁨day⁩ ago

    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.

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

    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.
