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.

Edit: Due to people aski g for it: here is the top ten of my ranking:

Here's how I defined the entropy value for each flag:

def color_weighted_spectral_entropy(image):
    b_channel, g_channel, r_channel = cv2.split(image)
    
    # Calculate spectral entropy for each channel
    def channel_spectral_entropy(channel):
        f_transform = np.fft.fft2(channel)
        f_shifted = np.fft.fftshift(f_transform)
        magnitude_spectrum = np.abs(f_shifted)
        if np.sum(magnitude_spectrum) > 0:
            normalized = magnitude_spectrum / np.sum(magnitude_spectrum)
        else:
            normalized = magnitude_spectrum
        # Entropy calculation with color channel weighting
        epsilon = 1e-10
        entropy = -np.sum(normalized * np.log2(normalized + epsilon))
        
        return entropy
    
    weighted_entropy = (
        0.333 * channel_spectral_entropy(b_channel) +
        0.333 * channel_spectral_entropy(g_channel) +
        0.333 * channel_spectral_entropy(r_channel)
    )
    
    return float(weighted_entropy)

"White_field" is just an array that holds zeroes. I use this as a sanity check. Code is on github. I can send DM to whomever is interested. I guess it can also be searched for.

Star Wars!

When my son joined Cub Scouts, we went to our first big Cub event, some big potluck dinner, and I sat next to a kid with a Star Wars t-shirt. I love Star Wars, saw the first movie in the theater, and have been a fan my whole life, so I asked, "You a Star Wars fan?" And he started talking, and so did I.

We were having a nice conversation about Star Wars, when his mother came up and said "Are you talking about Star Wars again? What did we say about that? You can't just start talking to random strangers about Star Wars!"

I responded, "No, you don't understand, I asked him about it. I love Star Wars, too," and the kid looked really happy that I'd defended him.

His mom said, "You don't understand, he has Asbergers, he'll NEVER stop talking about it," which didn't sound so bad to me, I had lots to talk about with this kid, he was a big fan, and knew his stuff.

We parted, but I've wondered ever since if I have Asperger's about Star Wars, too. Probably Music, too.
