Enum MergeMode 

pub enum MergeMode {
    KeepBest,
    Union,
}

What the tiled-detection merge emits for a group of boxes the match metric has joined.

Measured on the Ocean Cleanup ADIS 4K validation set (TOP2-836), the enclosing union cost about 0.05 AP50 on every frame (whole frame: 0.491 AP50 with plain NMS, 0.437 after the union merge, 0.490 with keep-best; 28-tile pipeline: 0.500 keep-best vs 0.442 union), so Self::KeepBest is the default. See the module docs.

Variants

KeepBest

Keep the group’s highest-scoring box — its coordinates and its score — and drop the boxes it matched. Greedy NMS under the configured metric. Default.

The kept box is never grown, rescored or relabelled. It is emitted canonicalized, which every box entering the merge is, so it differs from the input only for a degenerate input box whose min exceeded its max.

Union

Replace the group with its enclosing union carrying the group’s max score: the original GREEDYNMM merge (ModelPack metrics/tiled.py before merge_mode). Opt-in; inflates boxes and costs mAP.
