Struct EfMergeConfig 

#[repr(C)]
pub struct EfMergeConfig {
    pub metric: u32,
    pub threshold: f32,
    pub class_agnostic: c_int,
    pub max_det: usize,
    pub score_threshold: f32,
    pub mode: u32,
}

How overlapping detections from neighbouring tiles are merged.

Fields

metric: u32

0 = IoU, 1 = Intersection-over-Smaller.

IoS is the default for a reason: an object split across a tile seam has low IoU with its own fragment but high IoS, so IoU would keep both halves as separate detections.

threshold: f32

class_agnostic: c_int

Non-zero to merge across classes.

max_det: usize

score_threshold: f32

mode: u32

0 = keep-best (default): the highest-scoring box of each matched group is kept and the boxes it matched are dropped. 1 = union: the group becomes its enclosing union carrying the max score.

Keep-best is 0, but note that a zero-initialised struct is still not the library default: metric defaults to 1 (IoS), so an all-zero struct selects IoU. Fill with ef_merge_config_default. The union measured about 0.05 AP50 worse on every frame of the Ocean Cleanup ADIS 4K validation (TOP2-836), which is why it is opt-in.

Occupies what was this struct’s 4-byte tail pad, so adding it left every other field’s offset and the 32-byte size unchanged.
