Struct RetainedIous 

pub struct RetainedIous { /* private fields */ }

Per-(category, image) IoU matrices retained from a crate::evaluate_with pass when the caller passed crate::EvaluateParams::retain_iou = true.

Keyed by (k, i) (not (k, a, i)): IoU is geometry-only, so the same matrix serves every area range. The streaming evaluator preserves the same key shape so its retention store and the batch path stay drop-in compatible.

Implementations

impl RetainedIous

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

True when no matrices retained.

pub fn get(&self, k: usize, i: usize) -> Option<ArrayView2<'_, f64>>

Borrow the IoU matrix for (k, i) if retained.
