ExtractBlobs_Dynamic
Segments an image into blobs by dynamic thresholding.
| Name | Type | Description | |
|---|---|---|---|
 |
inImage | Image | Image from which blobs are extracted |
|
inRoi | Region* | Range of pixels to be processed |
|
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 | 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 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
Examples
 |
 |
ExtractBlobs_Dynamic performed on the sample image with inThresholdParams.MaxRelativeValue = -5.0 and inRegionProcessingParams.ClosingRadius = 3
Complexity Level
This filter is available on Basic Complexity Level.
Filter Group
This filter is member of ExtractBlobs filter group.
