Detailed Description

Public facade for attribute computation.

This class is the public facade of the attribute framework. It provides:

routing to AttributePipeline for ordinary valuedTree/topology requests;
cache-aware materialisation of one attribute, one group, or several heterogeneous requests at once inside the implementation;
projection from the internal MorphologicalTree node-id space to other public node-id spaces such as the preserved imported Higra convention;
convenience helpers that project node attributes back to the image domain.

The surrounding attribute subsystem is organised around:

AttributeNames / NodeAttributeSampleLayout for flat-buffer layout;
typed attribute kernels for concrete attribute families;
AttributeResultTypes.hpp for owning public results;
AttributePipeline / TopologyAttributeBackend for ordinary requests.

Ordinary public attribute computation is expressed through ValuedMorphologicalTree<T> or ValuedMorphologicalTreeView<T>, so altitude-dependent requests always carry an explicit altitude contract. Plain MorphologicalTree remains public only for topology-only requests.

The canonical execution space is always the tree's dense internal node-id space. Projection to the preserved imported Higra space only happens at the boundary of the public API. Attribute value buffers are materialized as float by default; public methods can select any std::floating_point output Real type, with double supported by the packaged Python bindings. The public Real controls result storage. Ordinary facade computations run their internal attribute pipeline in double and cast only at the API boundary.

inlinestatic

Projects a node attribute from a valued-tree view to a pixel image.

◆ computeAttributes() [1/2]

template<std::floating_point Real, AltitudeValue T>

ComputedAttributeData< Real > mmcfilters::AttributeComputation::computeAttributes	(	const ValuedMorphologicalTree< T > &	tree,
		const std::vector< AttributeOrGroup > &	attributes,
		NodeIdSpace	outputSpace = `NodeIdSpace::MorphologicalTree`
	)

inlinestatic

Computes a heterogeneous set of scalar attributes and attribute groups in one coordinated run.

Requests are routed to AttributePipeline. That path combines typed altitude kernels with the topology backend and returns a single layout containing exactly the requested scalar attributes.

Template Parameters

T	Altitude type owned by `tree`.

Parameters

tree	Valued tree supplying topology and dense altitude data.
attributes	Scalar attributes and groups to compute.
outputSpace	Node-id space requested for the returned buffer.

Returns: Owning node-major attribute data projected to outputSpace.

Definition at line 521 of file AttributeComputation.hpp.

◆ computeAttributes() [2/2]

template<std::floating_point Real, AltitudeValue T>

ComputedAttributeData< Real > mmcfilters::AttributeComputation::computeAttributes	(	const ValuedMorphologicalTreeView< T > &	tree,
		const std::vector< AttributeOrGroup > &	attributes,
		NodeIdSpace	outputSpace = `NodeIdSpace::MorphologicalTree`
	)

inlinestatic

Computes several scalar attributes and groups on a non-owning valued-tree view.

Template Parameters

T	Altitude type borrowed by `tree`.

Parameters

tree	Valued-tree view supplying topology and dense altitude data.
attributes	Scalar attributes and groups to compute.
outputSpace	Node-id space requested for the returned buffer.

Returns: Owning node-major attribute data projected to outputSpace.

Exceptions

std::runtime_error If the borrowed topology changed since view construction.

Definition at line 527 of file AttributeComputation.hpp.

◆ computeAttributesFromAltitudeSpan()

template<std::floating_point Real, AltitudeValue T>

ComputedAttributeData< Real > mmcfilters::AttributeComputation::computeAttributesFromAltitudeSpan	(	const ValuedMorphologicalTreeView< T > &	valuedTree,
		const std::vector< AttributeOrGroup > &	attributes,
		NodeIdSpace	outputSpace = `NodeIdSpace::MorphologicalTree`
	)

inlinestatic

Computes attributes over an external altitude span.

Attributes that read altitude use templated kernels. Attributes that are independent from altitude are delegated to the topology backend, avoiding an altitude copy or conversion. ValuedMorphologicalTreeView<T> is the named non-owning form of the same topology plus external-altitude contract.

Template Parameters

T	Altitude type borrowed by `valuedTree`.

Parameters

valuedTree	Valued-tree view supplying topology and dense altitude data.
attributes	Scalar attributes and groups to compute.
outputSpace	Node-id space requested for the returned buffer.

Returns: Owning node-major attribute data projected to outputSpace.

tree	Valued tree defining the current exported Higra hierarchy.
