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.

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 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.

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.

Simplicity I suppose. Colour combination. In my opinion if i can draw it from memory it’s a good flag.

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 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.

Don’t remember the movie or show but on aired in Korea I saw they would blur out parts such as cigarettes as well as arm pits (male actor) and a chef’s knife (prop was being held with the actors intention to defend herself).

One day he was going on about Kiki, how she does things in a certain way and I kept him going by say how interesting it was. He then turned to me and asked “You know that Kiki isn’t real, right, I made her up?”. He doesn’t like lying or being lied to, so within that frame I guess he wanted me to confirm that it was just play.

Our child has one. Her name is Kiki and she lives on a farm where she drives her tractors in a village called Plamplams. She speaks also an imaginary language. It seems like she represents experience he lives through vicariously expressing some image he has on how he fits in this world. We as his parents have always encouraged him; it is wonderful how he develops such creative images.
