◆ computePersistenceSensitivePropagation()

template<typename IT , typename DT , typename TT >
int ttk::lts::LocalizedTopologicalSimplification::computePersistenceSensitivePropagation ( Propagation< IT > &  propagation,
Propagation< IT > **  propagationMask,
IT *  segmentation,
IT *  queueMask,
const TT *  triangulation,
const IT *  order,
const DT *  scalars,
const DT  persistenceThreshold 
) const
inline

Basically the same as the simple propagation procedure, except that a propagation keeps track of the persistence of the computed propagation. As soon as the persistence strictly exceeds the given threshold the propagation is aborted.

Definition at line 349 of file LocalizedTopologicalSimplification.h.

◆ computePersistenceSensitivePropagations()

template<typename IT , typename DT , class TT >
int ttk::lts::LocalizedTopologicalSimplification::computePersistenceSensitivePropagations ( std::vector< Propagation< IT > > &  propagations,
Propagation< IT > **  propagationMask,
IT *  segmentation,
IT *  queueMask,
const TT *  triangulation,
const IT *  order,
const DT *  scalars,
const DT  persistenceThreshold 
) const
inline

This method computes (optionally in parallel) a list of persistence-sensitive propagations.

Definition at line 519 of file LocalizedTopologicalSimplification.h.

◆ computeSegment()

template<typename IT , class TT >
int ttk::lts::LocalizedTopologicalSimplification::computeSegment ( IT *  segmentation,
Propagation< IT > *  propagation,
const IT *  order,
const TT *  triangulation 
) const
inline

This method computes the domain segment of a given propagation. To this end, it stores a list of all segment vertices on the propagation data structure, and adds labels to the segmentation array.

Definition at line 607 of file LocalizedTopologicalSimplification.h.

◆ computeSegments()

template<typename IT , class TT >
int ttk::lts::LocalizedTopologicalSimplification::computeSegments ( IT *  segmentation,
std::vector< Propagation< IT > * > &  propagations,
const IT *  order,
const TT *  triangulation 
) const
inline

This method computes the segments of a given list of propagations.

Definition at line 666 of file LocalizedTopologicalSimplification.h.

◆ computeSimplePropagation()

template<typename IT , typename TT >
int ttk::lts::LocalizedTopologicalSimplification::computeSimplePropagation ( Propagation< IT > &  propagation,
Propagation< IT > **  propagationMask,
IT *  segmentation,
IT *  queueMask,
const TT *  triangulation,
const IT *  order 
) const
inline

This is a simple superlevel set propagation procedure that just absorbs the largest neighbor of the current set until the propagation encounters a saddle. To gain additional speedup this procedure keeps track of vertices that have already been added to the Fibonacci heap via the queueMask (duplicate entries slow down the heap).

Definition at line 227 of file LocalizedTopologicalSimplification.h.

◆ computeSimplePropagations()

template<typename IT , class TT >
int ttk::lts::LocalizedTopologicalSimplification::computeSimplePropagations ( std::vector< Propagation< IT > > &  propagations,
Propagation< IT > **  propagationMask,
IT *  segmentation,
IT *  queueMask,
const TT *  triangulation,
const IT *  inputOrder 
) const
inline

This method computes (optionally in parallel) a list of simple propagations.

◆ detectAndRemoveNonPersistentMaxima()

template<typename IT , typename DT , class TT >
int ttk::lts::LocalizedTopologicalSimplification::detectAndRemoveNonPersistentMaxima ( DT *  scalars,

std::vector< Propagation< IT > > &  propagations,
std::vector< std::tuple< IT, IT, IT > > &  sortedIndices,

const DT  persistenceThreshold 
) const
inline

Definition at line 1198 of file LocalizedTopologicalSimplification.h.

◆ detectAndRemoveUnauthorizedMaxima()

template<typename IT , class TT >
int ttk::lts::LocalizedTopologicalSimplification::detectAndRemoveUnauthorizedMaxima ( IT *  order,
IT *  segmentation,
IT *  queueMask,
IT *  localOrder,
Propagation< IT > **  propagationMask,
std::vector< Propagation< IT > > &  propagations,
std::vector< std::tuple< IT, IT, IT > > &  sortedIndices,
const TT *  triangulation,
const IT *  authorizedExtremaIndices,
const IT &  nAuthorizedExtremaIndices 
) const
inline

Definition at line 1115 of file LocalizedTopologicalSimplification.h.

◆ finalizePropagations()

template<typename IT >
int ttk::lts::LocalizedTopologicalSimplification::finalizePropagations ( std::vector< Propagation< IT > * > &  parentPropagations,
std::vector< Propagation< IT > > &  propagations,
const IT  nVertices 
) const
inline

This method identifies from a set of propagations so-called parent propagations, which are those propagations that either terminated at a saddle who has larger unvisited neighbors, or that were merged into a propagation that was aborted (during persistence-sensitive simplification).

Definition at line 567 of file LocalizedTopologicalSimplification.h.

◆ flattenOrder()

template<typename IT >
int ttk::lts::LocalizedTopologicalSimplification::flattenOrder ( IT *  outputOrder,
const std::vector< Propagation< IT > * > &  parentPropagations 
) const
inline

Definition at line 973 of file LocalizedTopologicalSimplification.h.

◆ flattenScalars()

template<typename DT , typename IT >
int ttk::lts::LocalizedTopologicalSimplification::flattenScalars ( DT *  scalars,
const std::vector< Propagation< IT > > &  propagationsA,
const std::vector< Propagation< IT > > &  propagationsB = {} 
) const
inline

Definition at line 1002 of file LocalizedTopologicalSimplification.h.

◆ initializeMemory()

template<typename IT >
int ttk::lts::LocalizedTopologicalSimplification::initializeMemory ( IT *  segmentation,
IT *  queueMask,
IT *  localOrder,
Propagation< IT > **  propagationMask,
const IT &  nVertices 
) const
inline

This method initializes all temporary memory for LTS procedures (assumes memory is already allocated).

Definition at line 94 of file LocalizedTopologicalSimplification.h.

◆ initializePropagations()

template<typename IT , class TT >
int ttk::lts::LocalizedTopologicalSimplification::initializePropagations ( std::vector< Propagation< IT > > &  propagations,
IT *  authorizationMask,
IT *  maximaBuffer,
const IT *  authorizedExtremaIndices,
const IT &  nAuthorizedExtremaIndices,
const IT *  order,
const TT *  triangulation 
) const
inline

This method iterates over an order array and detects all maxima, for which it will then initialize a propagation data structure. One can also pass a whitelist of authorized maxima that will be skipped. The maximaBuffer parameter needs to be big enough to fit all possible maxima indices (the buffer is explicitly exposed for memory reuse). Note, propagations are sorted in ascending order of their corresponding maxima.
