Struct Segmentation 

pub struct Segmentation {
    pub xmin: f32,
    pub ymin: f32,
    pub xmax: f32,
    pub ymax: f32,
    pub segmentation: Array3<u8>,
}

A segmentation result paired with the normalized bounding box that describes the spatial extent of segmentation.

The xmin/ymin/xmax/ymax fields describe the mask region — the proto-grid-aligned crop the [segmentation] tensor was sliced from. They are quantized to the proto grid step (1/proto_height and 1/proto_width, typically 1/160), so the region’s origin floors and its extent ceils relative to the companion DetectBox’s bbox. The detection bbox itself stays un-snapped (see EDGEAI-1304); use Segmentation bounds for rendering masks, and DetectBox.bbox for IoU evaluation, drawing detection rectangles, etc. The mask region always encloses the detection bbox.

Fields

xmin: f32

Left-most normalized coordinate of the mask region (proto-grid floor of the companion DetectBox.bbox.xmin).

ymin: f32

Top-most normalized coordinate of the mask region (proto-grid floor of the companion DetectBox.bbox.ymin).

xmax: f32

Right-most normalized coordinate of the mask region (proto-grid ceil of the companion DetectBox.bbox.xmax).

ymax: f32

Bottom-most normalized coordinate of the mask region (proto-grid ceil of the companion DetectBox.bbox.ymax).

segmentation: Array3<u8>

3D segmentation array of shape (H, W, C).

For instance segmentation (e.g. YOLO): C=1 — per-instance mask with continuous sigmoid confidence values quantized to u8 (0 = background, 255 = full confidence). Renderers typically threshold at 128 (sigmoid 0.5) or use smooth interpolation for anti-aliased edges.

For semantic segmentation (e.g. ModelPack): C=num_classes — per-pixel class scores where the object class is the argmax index.

Trait Implementations

impl Clone for Segmentation

fn clone(&self) -> Segmentation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Segmentation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Segmentation

fn default() -> Segmentation

Returns the “default value” for a type.

impl PartialEq for Segmentation

fn eq(&self, other: &Segmentation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
