ExtractBlobs_Intensity


Segments an image into blobs by thresholding.

Name Type Description
inImage Image Image from which blobs are extracted
inRoi Region* Range of pixels to be processed
inThresholdParams IntensityThresholdParams Parameters for thresholding an image
inRegionProcessingParams RegionProcessingParams Parameters for opening and closing of a region
inBlobSplittingParams BlobSplittingParams Parameters for splitting region into blobs
outBlobs RegionArray Blobs extracted from the input image
diagBlobAreas IntegerArray Areas of extracted blobs
diagBaseRegion Region Region of pixels right after thresholding

Description

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

  • image is thresholded by ThresholdToRegion 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

Examples

Description of usage of this filter can be found in examples and tutorial: Calibration World Coordinates On Original Images, Chocolate Cookies Inspection 3D, Nails, Screws and Nuts.

ExtractBlobs_Intensity performed on the sample image with inThresholdParams.MaxIntensity = 84.0 and inRegionProcessingParams.ClosingRadius = 10.

Complexity Level

This filter is available on Basic Complexity Level.

Filter Group

This filter is member of ExtractBlobs filter group.
