Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | AvlNet.Image | Input image. | |||
inRoi | AvlNet.NullableRef<AvlNet.Region> | Region of interest. Default value: atl::NIL. | |||
inRgbColor | AvlNet.Pixel | Color to compare the image to. | |||
inChromaAmount | float | <0.0f, 1.0f> | 0.7f | Proportion of chromatic information in distance computation. Default value: 0.7f. | |
inMaxDifference | float | <0.0f, INF> | 5.0f | Maximum difference between image pixel and model color. Default value: 5.0f. | |
inHysteresis | float | <0.0f, INF> | 0.0f | Defines how much the difference criterium is lowered for pixels neighboring with other foreground pixels. Default value: 0.0f. | |
outRegion | AvlNet.Region | Output region. |
Examples
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.
Hardware acceleration settings may be manipulated with Settings class.
