Merge projects

This command merges items from 2 or more projects and checks annotations for errors.

Spatial annotations are compared by distance and intersected, labels and attributes are selected by voting. Merge conflicts, missing items and annotations, other errors are saved into a .json file.

Usage:

datum merge --help

datum merge <project dirs>

Example: merge 4 (partially-)intersecting projects,

• consider voting succeeded when there are 3+ same votes
• consider shapes intersecting when IoU >= 0.6
• check annotation groups to have person, hand, head and foot (? for optional)

datum merge project1/ project2/ project3/ project4/ \
    --quorum 3 \
    -iou 0.6 \
    --groups 'person,hand?,head,foot?'
