ExtractBlobs_Dynamic

Module:	FoundationBasic

Segments an image into blobs by dynamic thresholding.

Name	Type	Description
inImage	Image	Image from which blobs are extracted
inRoi	ShapeRegion *	Range of pixels to be processed
inRoiAlignment	CoordinateSystem2D *	Adjusts the region
inThresholdParams	DynamicThresholdParams	Parameters for dynamic thresholding
inRegionProcessingParams	RegionProcessingParams	Parameters for opening and closing of a region
inBlobSplittingParams	BlobSplittingParams	Parameters for splitting region into blobs
outBlobs	Region Array	Blobs extracted from the input image
diagBlobAreas	Integer Array	Areas of extracted blobs
diagBaseRegion	Region	Region of pixels right after thresholding

This filter can be used to quickly segment an image with uneven illumination. It performs a series of operations on inImage:

image is thresholded by ThresholdToRegion_Dynamic using parameters from inThresholdParams
resulting region is opened and then closed by OpenRegion and CloseRegion using parameters from inRegionProcessingParams
resulting region is split into blobs by SplitRegionIntoBlobs using parameters from inBlobSplittingParams

ExtractBlobs_Dynamic performed on the sample image with inThresholdParams.MaxRelativeValue = -5.0 and inRegionProcessingParams.ClosingRadius = 3

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type	Description
DomainError	Region exceeds an input image in ExtractBlobs_Dynamic.

This filter is available on Basic Complexity Level.

This filter is member of ExtractBlobs filter group.
