Namespace: | FilNet |

Assembly: | FIL.NET.dll |
Syntax
C++
C#
public static void ExtractBlobs_Color ( FilNet.Image inImage, FilNet.ColorThresholdParams inThresholdParams, FilNet.PreSplitProcessingParams inProcessingParams, FilNet.SplittingParams inSplittingParams, IList<FilNet.Region> outBlobs, FilNet.Region outBaseRegion )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | FilNet.Image | Image from which blobs are extracted. | |||
inThresholdParams | FilNet.ColorThresholdParams | Parameters for color-based thresholding. | |||
inProcessingParams | FilNet.PreSplitProcessingParams | Parameters for postprocessing of the extracted region. | |||
inSplittingParams | FilNet.SplittingParams | Parameters for splitting region into blobs. | |||
outBlobs | System.Collections.Generic.IList<FilNet.Region> | Blobs extracted from the input image. | |||
outBaseRegion | FilNet.Region | Region of pixels right after thresholding. |
Description
This filter can be used to quickly segment an image using color-based thresholding. It performs a series of operations on inImage:
- image is thresholded by ThresholdToRegion_Color using parameters from inThresholdParams
- resulting region is opened and then closed by OpenRegion and CloseRegion, also holes are removed by FillRegionHoles using parameters from inProcessingParams
- resulting region is split into blobs by SplitRegionIntoBlobs using parameters from inSplittingParams
Examples
Errors
List of possible exceptions:
Error type | Description |
---|---|
DomainError | Region exceeds an input image in ExtractBlobs_Color. |
DomainError | Not supported inImage pixel format in ExtractBlobs_Color. Supported formats: 1xUInt8, 2xUInt8, 3xUInt8, 4xUInt8. |
