Annotation Instructions
Follow these steps to draw accurate bounding boxes:
Draw a rectangle around each unit.
Ignore background elements — skip labeling other gameplay elements (e.g. towers, spells, gravestones, dead units).
Make sure the box tightly fits the unit — extend to the leftmost, rightmost, topmost, and bottommost edges.
Don't label spells.
Box overlap is OK — don't worry if boxes intersect.
Label every troop — all gameplay units (e.g. troops, turrets, spawners, cloned units, buildings).
Even label unspawned troops- if you can clearly see the troop in the replay, draw a box around it.
