FillHoles()

Region oevislib_net.Region.FillHoles ( int inMinHoleArea = 1, Optional< int > inMaxHoleArea = null, RegionConnectivity inConnectivity = RegionConnectivity::EightDirections )

inline

Computes a new region, starting from the original and filling the holes with area in the requested range.

Parameters

inMinHoleArea	Holes with an area lower than this value will be neglected. Range: [0, +inf).
inMaxHoleArea	Holes with an area bigger than this value will be neglected. If negative, the parameter is not considered. Range: [0, +inf).
inConnectivity	Type of connectivity used by the algorithm.

Returns

The computed region.

RemoveBlobs()

Region oevislib_net.Region.RemoveBlobs ( RegionFeature inFeature = RegionFeature::Area, float inMinimum = 1::0f, Optional< float > inMaximum = null, RegionConnectivity inConnectivity = RegionConnectivity::EightDirections, bool inRemoveBoundaryBlobs = false )

inline

Computes a new region starting from the calling object and removing the blobs with the requested features.

Parameters

inFeature	Feature type used to filter blobs.
inMinimum	Blobs with a feature value lower than this will be neglected. Range [0, +inf).
inMaximum	Blobs with a feature value higher than this will be neglected. If Null, the parameter is neglected. Range [0, +inf).
inConnectivity	Type of connectivity used by the algorithm.
inRemoveBoundaryBlobs	If true, blobs that are touching the region frame will be removed, independently of their feature value.

Returns

The computed region.

RemoveBlobsOnRegionFrame()

Region oevislib_net.Region.RemoveBlobsOnRegionFrame ( Region inBorderRegion, RegionConnectivity inConnectivity )

inline

Removes the blobs of the calling object that are touching the frame of the provided region.

Parameters

inBorderRegion	Region whose frame is used to determine if the blobs must be deleted.
inConnectivity	Type of connectivity used by the algorithm.

Returns

The computed region.

RemoveBorders()

Region oevislib_net.Region.RemoveBorders ( int inMarginX = 0, int inMarginY = 0 )

inline

Computes a new region starting from the calling object and removing the requested margin from the outer borders.

Parameters

inMarginX	Margin from the horizontal borders. Range [0, +inf).
inMarginY	Margin from the vertical borders. Range [0, +inf).

Returns

The computed region.

SplitIntoBlobs()

Array< Region > oevislib_net.Region.SplitIntoBlobs ( int inMinBlobArea = 1, Optional< int > inMaxBlobArea = null, RegionConnectivity inConnectivity = RegionConnectivity::EightDirections, bool inRemoveBoundaryBlobs = false )

inline

Returns all the blobs that match the input parameters.

Parameters

inMinBlobArea	Blobs with an area lower than this value will be neglected. Range: [0, +inf).
inMaxBlobArea	Blobs with an area higher than this value will be neglected. If Null, the parameter is neglected. Range: [0, +inf).
inConnectivity	Type of connectivity used by the algorithm.
inRemoveBoundaryBlobs	If true, blobs that are touching the region's frame are neglected, regardless of their area value.

Returns

An array containing all the found blobs.

SplitIntoClusters() [1/2]

Array< Region > oevislib_net.Region.SplitIntoClusters ( int inClusters, int inMaxIterations = 100, int inAttempts = 1, KMeansInitialization inClustersInitialization = KMeansInitialization::KMeansPP, int inMinBlobArea = 1, Optional< int > inMaxBlobArea = null, bool inRemoveBoundaryBlobs = false )

inline

Splits the region into clusters.

Parameters

inClusters	Number of clusters in which to split the region. Range: [2, +inf).
inMaxIterations	Maximum number of iterations. Range: [1, +inf).
inAttempts	Number of times the algorithm is executed using different initial labels. The algorithm returns at the end the labels that yield the best compactness. Range: [1, +inf).
inClustersInitialization	Method used to initialize clusters' centroids.
inMinBlobArea	Blobs with an area lower than this value will be neglected. Range: [0, +inf).
inMaxBlobArea	Blobs with an area higher than this value will be neglected. If Null, the parameter is neglected. Range: [0, +inf).
inRemoveBoundaryBlobs	If true, blobs that are touching the region's frame are neglected, regardless of their area value.

Returns

An array containing all the found blobs.

SplitIntoClusters() [2/2]

Array< Region > oevislib_net.Region.SplitIntoClusters ( int inMinPoints, float inEpsilon, bool inIgnoreOutliers = true, int inMinBlobArea = 1, Optional< int > inMaxBlobArea = null, bool inRemoveBoundaryBlobs = false )

inline

Splits the region into clusters.

Parameters

inMinPoints	Minimum number of neighbors to create a cluster from a point. Range: [1, +inf).
inEpsilon	Maximum distance between two points to be considered neighbors. Range: (0, +inf).
inIgnoreOutliers	If true, no errors are thrown if outliers are found.
inMinBlobArea	Blobs with an area lower than this value will be neglected. Range: [0, +inf).
inMaxBlobArea	Blobs with an area higher than this value will be neglected. If Null, the parameter is neglected. Range: [0, +inf).
inRemoveBoundaryBlobs	If true, blobs that are touching the region's frame are neglected, regardless of their area value.

Returns

An array containing all the found blobs.
