Set lookup table

Set look-up table (LUT) for an image or a specific channel of an image.

Description

Set look-up table (LUT) for an image or a specific channel of an image. The look-up table determines what colour ImageJ will render each intensity value of an image.

Parameters

Parameter Description
Input image Image to set look-up table for.
Channel mode Control if the same look-up table is applied to all channels, or just one:

- "All channels" Apply the same look-up table to all channels of the input image.

- "Specific channels" Only apply the look-up table to the channel specified by the "Channel" parameter. All other channels will remain unaffected.
Reference image
Channel When in "Specific channels" mode, this is the channel the look-up table will be applied to. Channel numbering starts at 1.
Lookup table Look-up table to apply to the relevant channels. Choices are: From RGB, From wavelength, Grey, Red, Green, Blue, Cyan, Magenta, Yellow, Fire, Ice, Jet, Physics, Random, Spectrum, Thermal.
Red component
Green component
Blue component
Wavelength (nm)
Display mode Controls how the minimum value in the look-up table should be rendered:

- "Full range" Use the full colour range of the look-up table. This is the default look-up table without modifications.

- "Set zero to black" Uses the standard look-up table, except for the lowest value, which is always set to black. This is useful for cases where the background will be 0 or NaN and should be rendered as black.
