Module: | FoundationBasic |
---|
Thresholds an image using two relative thresholds and produces two regions (Dark and Bright) in a single image pass.
Applications
This filter can replace two instances of ThresholdToRegion_Relative which may slightly improve performance.
Name | Type | Range | Description | |
---|---|---|---|---|
![]() |
inImage | Image | Input image | |
![]() |
inRoi | Region* | Region of interest | |
![]() |
inBaseImage | Image | Pixels of this image are subtracted from inImage before thresholding | |
![]() |
inDarkThreshold | Real | Maximum relative value of a pixel that is considered DarkRegion | |
![]() |
inBrightThreshold | Real | Minimum relative value of a pixel that is considered BrightRegion | |
![]() |
inHysteresis | Real | 0.0 - ![]() |
Defines how much the threshold criteria are lowered for pixels neighboring with other foreground pixels |
![]() |
outDarkRegion | Region | Region of pixels equal or lower than inDarkThreshold | |
![]() |
outBrightRegion | Region | Region of pixels equal or greater than inBrightThreshold |
Hardware Acceleration
This operation is optimized for SSE2 technology for pixels of types: 1xUINT8, 3xUINT8.
This operation supports automatic parallelization for multicore and multiprocessor systems.
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 | Image formats are not the same in ThresholdToRegion_Relative_DarkBright. |
DomainError | Image sizes are not equal in ThresholdToRegion_Relative_DarkBright. |
DomainError | Region exceeds an input image in ThresholdToRegion_Relative_DarkBright. |
Complexity Level
This filter is available on Expert Complexity Level.
Filter Group
This filter is member of ThresholdToRegion filter group.
