Intensity Transformation Tables

  The intensity transformation tables (ITTs) come between the image memories and the LUT and are emulated in the XWindow environment by convolving the ITT values with the current LUT. Interactive modification is done via the arrow keys.
The main commands which control the ITT functions are:

LOAD/ITT - load an ITT
CLEAR/ITT - bypass the ITT
SET/ITT - pass through an ITT
GET/ITT - read back an ITT
MODIFY/ITT - modify the ITT interactively

To display the ITT, use DISPLAY/LUT which shows the combined effect of LUT and ITT. Some of the currently available ITT tables are:

ramp
neg
expo
log
neglog
jigsaw
staircase

With the command TUTORIAL/ITT you can see the effect of ITTs and modify the ITTs interactively.
