MLModule¶

genre	`LUT`
status	`stable`
author	`Wolf Spindler`
package	`MeVisLab/Standard`
dll	`MLMiscModulesInv`
definition	MLMiscModulesInv.def
see also	`LutBase`, `View2D`, `SoRLVolRen`, `SoRLLookUpTable`, `SoView2DOverlay`
keywords	`grey`, `gray`, `red`, `green`, `blue`, `alpha`, `color`, `channel`, `lookup`, `table`, `rgb`, `rgba`, `conversion`, `transfer`, `function`

Purpose¶

The module Lut permits editing piecewise linear functions which defines a lookup table to map input voxel values to output voxel values or - as an alternativ - a window/center representation.

Note that due to performance reasons the maximum number of look up entries is limited to 16384. So the resolution of the table is limited if maximum and minimum value of the input image differ strongly. If maximum and minimum differ less or equal than 1 the number of look up table entries is set to 1024.

Usage¶

Use SoLUTEditor or SoLUTEditor2D instead.
