Purpose

The module LUTPrimitive generates a single-channel, parametrized lookup table (LUT) object that can be used with the ApplyLUT module or within 2D/3D viewers (in conjunction with SoMLLUT).

The basic LUT shapes offered by the LUTPrimitive module include Ramp, Wall, and Gaussian.

Details

See LUT Functions for general information about ML lookup tables.

Base Value: Double

Center: Double

Edge Width: Double

Peak Value: Double

Relative: Bool

Shape: Enum

Width: Double

Visible Fields

Shape

name: shape, type: Enum, default: Ramp

Defines the basic shape of the generated lookup table.

Values:

Title	Name
​Ramp	​Ramp
​Wall	​Wall
​Gauss	​Gauss
​Sigmoid	​Sigmoid

Relative

name: relative, type: Bool, default: TRUE

If checked, the generated LUT is relative, i.e., the index value interval [0, …, 1] is rescaled to the true image value range before applying the LUT. If the LUT is absolute, on the other hand, the image values are used as index values directly, without rescaling.

Center

name: center, type: Double, default: 0.5

Sets the center index value of the LUT shape, either as an absolute image value or relative to [0, …, 1].

Width

name: width, type: Double, default: 1

Sets the width value of the LUT shape, either as an absolute image value range or relative to [0, …, 1].

Edge Width

name: edgeWidth, type: Double, default: 0

Sets the width of the wall edges, either as an absolute image value range or relative to [0, …, 1] if the Shape is set to Wall.

Base Value

name: baseValue, type: Double, default: 0, minimum: 0, maximum: 1

Sets the base level (lowest level) of the lookup table.

Peak Value

name: peakValue, type: Double, default: 1, minimum: 0, maximum: 1

Sets the peak level (highest level) of the lookup table. For the Wall and Gauss shapes, this is the value obtained at the center of the LUT.
