Struct AssignResult 

Source 
pub struct AssignResult {
    pub is_positive: Vec<bool>,
    pub target_boxes: Vec<f32>,
    pub target_cls: Vec<usize>,
    pub soft_target: Vec<f32>,
}
Expand description

Result of assigning GT targets to anchors for a single image.

Fields§

§is_positive: Vec<bool>

Whether each anchor is a positive. Shape: [A].

§target_boxes: Vec<f32>

GT box (cx, cy, w, h) assigned to each anchor (only valid for positives). Shape: [4, A] channels-first.

§target_cls: Vec<usize>

GT class index assigned to each anchor (only valid for positives). Shape: [A].

§soft_target: Vec<f32>

Soft target per anchor: (align / max_align_for_gt) * max_iou_for_gt.

Zero for negatives. Used as the soft class label AND box loss weight, matching the ultralytics E2ELoss normalisation. Shape: [A].
