colour.models.eotf_DICOMGSDF(J: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1], in_int: bool = False, constants: Structure | None = None) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 1]

Apply the DICOM - Grayscale Standard Display Function electro-optical transfer function (EOTF).

Parameters:

• J (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – Just-Noticeable Difference (JND) Index, \(j\).

• in_int (bool) – Whether to treat the input value as integer code value or float equivalent of a code value at a specified bit-depth.

• constants (Structure | None) – DICOM - Grayscale Standard Display Function constants.

Returns:

Luminance \(L\).

Return type:

numpy.ndarray
