Python OpenCVにてcv2.cvtColorを使ってカラー対応表を作成しました。
- 変換に用いたコードは
cv2.COLOR_RGB2HSV、cv2.COLOR_RGB2Lab、cv2.COLOR_RGB2XYZです。 - HSVのH値（色相）は
cv2.COLOR_RGB2HSVを用いると0~179、cv2.COLOR_RGB2HSV_FULLを用いると0~254で出力されます。ここではcv2.COLOR_RGB2HSVを用いた0~179の値を載せています。 - XYZ,Labについては、RGB値がsRGBなので、リニアRGBに変換してから変換しています。
- XYZのuint8とfloatの関係は以下の通りです。
X(uint8) = X(float) \times 255 \\
Y(uint8) = Y(float) \times 255 \\
Z(uint8) = Z(float) \times 255
- Lab*のuint8とfloatの関係は以下の通りです。
L^*(uint8) = L^*(float) \times 2.55 \\
a*(uint8) = a^*(float) + 128 \\
b*(uint8) = b^*(float) + 128
色変換やリニアRGBについてはこちらが詳しいです。
