Morphology< TreeType >::NodeMaskOp Struct Reference

Node Mask dilation/erosion operations for individual leaf nodes on a given tree. The leaf node may optionally belong to a different tree than the provided accessor, which will have the effect of dilating the leaf node mask into a different tree, or eroding the node mask based on corresponding neighbors in a different tree.

void dilate ( LeafType &  leaf )

inline

Dilate a single leaf node by the current spatial scheme stored on the instance of this NodeMaskOp. Neighbor leaf nodes are also updated.

Unlike erode, dilate is expected to be called in a single threaded context as it will update the node masks of neighboring leaf nodes as well as the provided leaf.

Parameters

leaf	The leaf to dilate. The leaf's origin and value mask are used to calculate the result of the dilation.

void dilate ( LeafType &  leaf, const MaskType &  mask  )

inline

Dilate a single leaf node by the current spatial scheme stored on the instance of this NodeMaskOp. The provided mask is used in place of the actual leaf's node mask and applied to the leaf afterwards. Neighbor leaf nodes are also updated.

Unlike erode, dilate is expected to be called in a single threaded context as it will update the node masks of neighboring leaf nodes as well as the provided leaf.

Parameters

leaf	The leaf to dilate. The leaf's origin is used to calculate the result of the dilation.
mask	The node mask to use in place of the current leaf node mask.

MaskType erode ( const LeafType &  leaf )

inline

Erode a single leaf node by the current spatial scheme stored on the instance of this NodeMaskOp.

Unlike dilate, this method updates the provided mask and does not apply the result to the leaf node. The leaf node is simply used to infer the position in the tree to find it's neighbors. This allows erode to be called from multiple threads

Parameters

leaf	The leaf to erode. The leaf's origin is used to calculate the result of the erosion.

Returns

The eroded mask

void erode ( const LeafType &  leaf, MaskType &  mask  )

inline

Erode a single leaf node by the current spatial scheme stored on the instance of this NodeMaskOp. The provided mask is used in place of the actual leaf's node mask and stores the erosion result.

Unlike dilate, this method updates the provided mask and does not apply the result to the leaf node. The leaf node is simply used to infer the position in the tree to find it's neighbors.

Parameters

leaf	The leaf to erode. The leaf's origin is used to calculate the result of the erosion.
mask	The node mask to use in place of the current leaf node mask.
