volTrValues

Applies basic vol image transform from the input values to output values.

Usage: volTrValues –input <volFileName> –o <volOutputFileName> -s 1 99 -r 100 200

=> all voxels of values 1 (resp. 99) will be 100 (resp. 200) in the resulting image.

Allowed options are :

-h [ --help ]                     display this message.
-i [ --input ] arg                Input vol file.
-o [ --output ] arg (=output.vol) Output filename.
-s [ --inputVals ] arg            specify the values which will be 
                                  transformed with the output values (given 
                                  with --outputVals).
-r [ --outputVals ] arg           specify the output values to transformed 
                                  according to the input values (given with 
                                  --inputVals).

Example:

This tool can be useful to apply simple intensity transforms. For instance if you want to transform all intensities starting from 0 to 50 into interval 200 250 you can do as follows:

$ volTrValues -i $DGtal/examples/samples/lobster.vol -s {0..50} -r {200..250} -o lobsterTr.vol
$ 3dImageViewer -i  lobsterTr.vol

By using 3dImageViewer ou should obtain such a result:
