Parameters

Name Type Range Default Description
inImageAvl.ImageImage from which blobs are extracted.
inRoiAtl.Optional<Avl.Region>Range of pixels to be processed. Default value: atl::NIL.
inFrameSizeint<0, INF>1How many pixels from the region border are excluded from the results. Default value: 1.
inStdDevfloat<0.0f, INF>2.0fAmount of smoothing used by the edge filter. Default value: 2.0f.
inEdgeThresholdfloat<0.0f, INF>15.0fSufficient edge strength; edges of that strength will always be detected. Default value: 15.0f.
inEdgeHysteresisfloat<0.0f, INF>5.0fValue by which the edge threshold is decreased for edge points neighboring with sufficiently strong edges. Default value: 5.0f.
inMaxJoiningDistancefloat<0.0f, INF>0.0fMaximal distance between edges that can be joined. Default value: 0.0f.
inMinAreaint<0, INF>50Minimal area of a detected blob. Default value: 50.
inMaxAreaAtl.Optional<int><0, INF>Maximal area of a detected blob. Default value: atl::NIL.
inComputeNestingLevelsboolFlag indicating whether nesting levels should be computed.
inEdgeClosingint<0, INF>1Radius of enclosing small holes in the detected blobs. Default value: 1.
outBlobsSystem.Collections.Generic.List<Avl.Region>Blobs extracted from the input image.
outNestingLevelsAtl.Optional<System.Collections.Generic.List<int>>Nesting level of each extracted blob.
diagEdgeRegionAvl.Diagnostic<Avl.Region>Region of the found edges.
