itk_merge_discrete_labels

Merge multiple discrete label volumes by overlay (non-zero overwrite).

itk_merge_discrete_labels input_1.mnc [input_2 ...] <output.mnc>

DESCRIPTION

itk_merge_discrete_labels merges multiple discrete label volumes into a single output volume by sequential overlay. Each input volume is applied in order: non-zero voxels in later volumes overwrite values from earlier ones. This simple overlay strategy is useful for combining partial segmentations that cover non-overlapping or priority-ordered regions.

Input files can also be specified via a CSV file. The output data type can be set to byte or short integer.

OPTIONS

--csv input

Read input file paths from a CSV file (one path per line).

--clobber

Overwrite the output file if it already exists.

--byte

Store output voxels as unsigned byte.

--short

Store output voxels as short integer.

EXAMPLES

# Merge two label volumes (later volumes take priority)
itk_merge_discrete_labels base_labels.mnc overlay_labels.mnc merged.mnc

# Merge multiple volumes
itk_merge_discrete_labels seg1.mnc seg2.mnc seg3.mnc merged.mnc --short

# Merge from a file list
itk_merge_discrete_labels --csv file_list.csv merged.mnc
