Detailed Description

Shape descriptors of the region enclosed by the external boundary.

Holes are filled and each enclosed pixel has unit mass at its center. Computation consumes one incremental trace traversal without storing filled masks or retaining traces. Every live node must have exactly one external boundary. Altitude is used only to select connectivity for lower/upper shapes.

Member Function Documentation

compute() [1/2]

template<std::floating_point Real, AltitudeValue T>

static void mmcfilters::attributes::computers::FilledShapeAttributeComputer::compute ( const AltitudeAttributeComputeContext< Real, T > &  context )

inlinestatic

Computes descriptors using altitudes to resolve directional connectivity.

Parameters

context

Valued tree, requests, and destination columns.

Definition at line 102 of file FilledShapeAttributeComputer.hpp.

compute() [2/2]

template<std::floating_point Real>

static void mmcfilters::attributes::computers::FilledShapeAttributeComputer::compute ( const AttributeComputeContext< Real > &  context )

inlinestatic

Computes requested filled-region descriptors.

Parameters

context

Tree, requests, and destination columns.

Definition at line 91 of file FilledShapeAttributeComputer.hpp.

computeUnitRows()

template<std::floating_point Real>

static void mmcfilters::attributes::computers::FilledShapeAttributeComputer::computeUnitRows ( const UnitAttributeComputeContext< Real > &  context )

inlinestatic

Writes unit-support values in the supplied pixel order.

Area, eccentricity, and circularity are one; the centroid is the pixel coordinate. All remaining descriptors are zero.

Parameters

context

Pixel order, requests, and destination columns.
