Struct TiledFrameAccumulator 

pub struct TiledFrameAccumulator { /* private fields */ }

Streaming collector for one frame’s tiled detections. A pipelined runtime pushes each tile’s per-tile-decoded boxes as inference completes (any order), then finalizes once every tile has arrived — the “collect after the final tile” fan-in. Not internally synchronized; keep one accumulator per in-flight frame.

Implementations

impl TiledFrameAccumulator

pub fn new( frame_dims: (f32, f32), tiles_total: usize, cfg: MergeConfig, est_per_tile: usize, ) -> Self

Create an accumulator for a frame with tiles_total tiles. frame_dims is (frame_w, frame_h) in pixels, used by Self::finalize_normalized. est_per_tile pre-reserves the detection buffer.

Examples

use edgefirst_decoder::tiling::{MergeConfig, TiledFrameAccumulator};
let acc = TiledFrameAccumulator::new((1920.0, 1080.0), 12, MergeConfig::default(), 16);
assert_eq!(acc.remaining(), 12);
assert!(!acc.is_complete());

pub fn push_tile( &mut self, tile_boxes: Vec<DetectBox>, placement: &TilePlacement, ) -> bool

Lift one tile’s per-tile-decoded boxes to full-frame pixels and append them. Idempotent per placement.index: a duplicate, out-of-range, or foreign placement (one whose count disagrees with this accumulator’s tiles_total, i.e. from a different plan/frame) is ignored and its boxes dropped, so out-of-order and at-least-once delivery both converge to the same result. Returns true if the tile was newly accepted, false otherwise.

pub fn is_complete(&self) -> bool

True once every tile of the frame has been pushed (by distinct index).

pub fn remaining(&self) -> usize

Tiles still outstanding.

pub fn finalize(self) -> Vec<DetectBox>

Merge all accumulated detections into full-frame pixel boxes.

pub fn finalize_normalized(self) -> Vec<DetectBox>

Merge then renormalize to [0,1] by frame_dims (for the tracker, matching the non-tiled normalized-detection contract).

Returns an empty list when frame_dims are non-finite or non-positive rather than emitting Inf/NaN coordinates.
