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.
Complexity Level
This filter is available on Basic Complexity Level.
Filter Group
This filter is member of ExtractBlobs filter group.
