Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inMergingMethodFilNet.BlobMergingMethodNeighborDefines a criterion by which two pixels can be merged into one blob. Default value: Neighbor.
inConnectivityFilNet.RegionConnectivity
inMaxDifferenceint<0, INF>5Maximal tonal difference that allows two pixels to be merged into one blob. Default value: 5.
inHysteresisintChange of MaxDifference between first and second iteration.
inTonalDriftboolTrueWhen 'True' blobs can be merged even if the illumination is not even. Default value: True.
inDirectionalboolWhen 'True' the filter can segment results of GradientDirAndPresenceImage.
inMinAreaint<0, INF>20Minimal area of a blob that may be accepted. Default value: 20.
outBlobsSystem.Collections.Generic.IList<FilNet.Region>

Description

The filter segments the inImage image in two phases. In the first step segmentation is done within tiles, while in the second step blobs are merged between consecutive tiles.

Errors
