What image entropy measures

Shannon entropy rises when pixel values are distributed across more levels with less predictability. Flat graphics tend to score lower, while detailed photos, texture, and noise often score higher. Entropy describes distribution complexity, not visual quality by itself.

자주 묻는 질문

What is the maximum entropy for an 8-bit channel?

The theoretical maximum is 8 bits when all 256 values occur with equal probability.

Does high entropy mean a better image?

No. Detail can increase entropy, but unwanted noise can increase it too.
