Adaptation


class Adaptation
ColorSpace.Adaptation.BRADFORD

Bradford chromatic adaptation transform, as defined in the CIECAM97s color appearance model.

ColorSpace.Adaptation.CIECAT02

CIECAT02 chromatic adaption transform, as defined in the CIECAM02 color appearance model.

ColorSpace.Adaptation.VON_KRIES

von Kries chromatic adaptation transform.

List of adaptation matrices that can be used for chromatic adaptation using the von Kries transform. These matrices are used to convert values in the CIE XYZ space to values in the LMS space (Long Medium Short).

Given an adaptation matrix A, the conversion from XYZ to LMS is straightforward:

[LMS]=A[XYZ]

The complete von Kries transform T uses a diagonal matrix noted D to perform the adaptation in LMS space. In addition to A and D, the source white point W1 and the destination white point W2 must be specified:

[L1M1S1]=A[W1XW1YW1Z] [L2M2S2]=A[W2XW2YW2Z] D=[L2L100 0M2M10 00S2S1] T=A1.D.A

As an example, the resulting matrix T can then be used to perform the chromatic adaptation of sRGB XYZ transform from D65 to D50:

sRGBD50=T.sRGBD65
