Description

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

Examples

ExtractBlobs_Dynamic performed on the sample image with inThresholdParams.Polarity = Dark, inThresholdParams.Threshold = 5.0, and inProcessingParams.ClosingRadius = 3

Errors

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.

Complexity Level

This filter is available on Basic Complexity Level.

Filter Group
