Subtracts a scalar value from each pixel.
Name | Type | Description | |
---|---|---|---|
inImage | Image | Input image | |
inRoi | Region* | Range of pixels to be processed | |
inValue | Real | Value to be subtracted | |
outImage | Image | Output image |
Description
The operation decreases the brightness of the inImage by subtracting a fixed value from each of its pixels.
Whenever the resulting value exceeds the range of pixel values, it is clipped to the nearest proper value.
Examples
Hardware Acceleration
This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT8, SINT16, REAL.
This operation supports automatic parallelization for multicore and multiprocessor systems.
Complexity Level
This filter is available on Basic Complexity Level.
