RGB 값을 255로 정규화해야 할까, 256으로 정규화해야 할까?

The choice between 255 and 256 normalization is a fundamental decision in image processing that balances GPU-native efficiency with mathematical precision. While the 256-method offers slightly better theoretical error rates, adhering to the 255-standard ensures seamless compatibility and lossless round-trip conversions for real-world applications. This distinction is vital for engineers building high-fidelity graphics pipelines or AI-driven image manipulation tools where color integrity is paramount.
