Struct ConnectedStatsPrimitive 

pub struct ConnectedStatsPrimitive<B>
where
    B: Backend,
{
    pub area: <B as BackendTypes>::IntTensorPrimitive,
    pub left: <B as BackendTypes>::IntTensorPrimitive,
    pub top: <B as BackendTypes>::IntTensorPrimitive,
    pub right: <B as BackendTypes>::IntTensorPrimitive,
    pub bottom: <B as BackendTypes>::IntTensorPrimitive,
    pub max_label: <B as BackendTypes>::IntTensorPrimitive,
}

Primitive version of ConnectedStats, to be returned by the backend.

Accelerated Cube operations reserve height * width entries for each statistics array. CPU fallbacks return one entry per component, including background. Fusion retains image-sized metadata for these arrays even on CPU fallback, preserving the existing discrepancy with their compact data. max_label has one entry.

Fields

area: <B as BackendTypes>::IntTensorPrimitive

Total area of each component

left: <B as BackendTypes>::IntTensorPrimitive

Leftmost x coordinate in the component

top: <B as BackendTypes>::IntTensorPrimitive

Topmost y coordinate in the component

right: <B as BackendTypes>::IntTensorPrimitive

Rightmost x coordinate in the component

bottom: <B as BackendTypes>::IntTensorPrimitive

Bottommost y coordinate in the component

max_label: <B as BackendTypes>::IntTensorPrimitive

Scalar tensor of the max label

Trait Implementations

impl<B> ExtensionType<B> for ConnectedStatsPrimitive<B>

where B: Backend,

type Target = ConnectedStatsPrimitive<Dispatch>

The target struct layout where all internal concrete backend tensors are transformed into DispatchTensors.

fn map_to_dispatch<F>( self, map_kind: F, autodiff: DispatchAutodiffContext, ) -> <ConnectedStatsPrimitive<B> as ExtensionType<B>>::Target

where F: Fn(BackendTensor<B>) -> DispatchTensorKind,

Transforms the internal fields of the struct by applying a backend-specific wrapping closure.

fn map_from_dispatch<F>( target: <ConnectedStatsPrimitive<B> as ExtensionType<B>>::Target, unwrap_kind: F, ) -> ConnectedStatsPrimitive<B>

where F: Fn(DispatchTensor) -> BackendTensor<B>,

Reconstruct the concrete Struct<B> from its dispatch form Struct<Dispatch>.

fn routing_tensor( target: &<ConnectedStatsPrimitive<B> as ExtensionType<B>>::Target, ) -> Option<&DispatchTensor>

Return a tensor of the dispatch form to use for routing, or None if this value currently holds no tensor (e.g. an enum on a tensor-less variant).

fn routing_float_tensor( target: &<ConnectedStatsPrimitive<B> as ExtensionType<B>>::Target, ) -> Option<&DispatchTensor>

Like routing_tensor but returns only a float tensor, or None if there is none.
