Member Function Documentation

LabToRgb8()

static Image LabToRgb8 ( Image imgLab, Interpolator interpolator )

static

Converts a Lab image to a sRGB 8bit image.

Parameters

imgLab	3-planed float/double image containing Lab values.
interpolator	Spectral interpolator to be used during conversion.

Returns

3-planed uint8 image containing the values of sRGB (R-value in plane 0, G-value in plane 1, B-value in plane 2).

ToLab()

static Image ToLab ( this Cube cube, Interpolator interpolator )

static

Converts a normalized cube to a Lab image.

Parameters

cube	Normalized cube. Number of bands in the cube must match with the number of bands in the interpolator.
interpolator	Spectral interpolator to be used during conversion.

Returns

3-planed float image containing the values of Lab (L-value in plane 0, a-value in plane 1, b-value in plane 2).

ToXYZ()

static Image ToXYZ ( this Cube cube, Interpolator interpolator )

static

Converts a normalized cube to a XYZ image.

Parameters

cube	Normalized cube. Number of bands in the cube must match with the number of bands in the interpolator.
interpolator	Spectral interpolator to be used during conversion.

Returns

3-planed float image containing the values of XYZ (X-value in plane=0, Y-value in plane=1, Z-value in plane=2).

XyzToLab()

static Image XyzToLab ( Image imgXYZ, Interpolator interpolator )

static

Converts an XYZ image to Lab.

Parameters

imgXYZ	3-planed float/double image containing XYZ values.
interpolator	Spectral interpolator to be used during conversion.

Returns

3-planed float image containing the values of Lab (L-value in plane 0, a-value in plane 1, b-value in plane 2).
