threshold_volume

create a label volume by thresholding an input MINC volume

threshold_volume input.mnc labels.mnc|labels.tag min_value max_value label_value [out.mnc] | [min_value2 max_value2] | [-crop] ...

DESCRIPTION

threshold_volume creates a label volume (or tag file) from an input MINC volume. Voxels whose intensity values fall between min_value and max_value (inclusive) are assigned label_value in the output. All other voxels are set to zero.

The output can be written to a MINC volume or a tag file, depending on the extension of the second argument.

Multiple threshold ranges can be specified by providing additional min_value and max_value pairs on the command line. Each range uses the same label_value.

If -crop is specified, the output volume is cropped to the bounding box of the labelled voxels.

If out.mnc is specified as an additional argument, the result is written to that file instead of overwriting the labels file.

EXAMPLES

threshold_volume input.mnc labels.mnc 100 200 1

threshold_volume input.mnc labels.mnc 100 200 1 -crop

threshold_volume input.mnc labels.mnc 50 100 1 150 200 2
