Reverts the pixel value range (unsigned) or applies numeric negation (signed).
Name | Type | Description | |
---|---|---|---|
inImage | Image | Input image | |
inRoi | Region* | Range of pixels to be processed | |
outImage | Image | Output image |
Description
The operation negates the pixel values of the inImage. Depending on the pixel type, the negation is defines as follows:
- For the signed pixel types:
- For the unsigned pixel types: (which can be thought of as mirroring the pixel values around the center of the pixel values range)
Examples
Description of usage of this filter can be found in examples and tutorial: Image Modification Using the HMI.
Hardware Acceleration
This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT8, SINT16, REAL NEON: UINT8, SINT8, UINT16, SINT16, SINT32, REAL.
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 | Region exceeds an input image in NegateImage. |
