Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inRoiAvlNet.ShapeRegionLocation at which object presence is being checked.
inRoiAlignmentAvlNet.CoordinateSystem2D?Adjusts the region of interest to the position of the inspected object. Default value: atl::NIL.
inColorModelAvlNet.HSxColorModelSelected color model.
inBeginHueint<0, 255>0Begin of the range of acceptable hue. Default value: 0.
inEndHueint<0, 255>255End of the range of acceptable hue. Default value: 255.
inMinSaturationint<0, 255>128Lowest acceptable saturation. Default value: 128.
inMaxSaturationint?<0, 255>Highest acceptable saturation. Default value: atl::NIL.
inMinBrightnessfloat?<0.0f, INF>128.0fLowest acceptable brightness. Default value: 128.0f.
inMaxBrightnessfloat?<0.0f, INF>Highest acceptable brightness. Default value: atl::NIL.
inMinAmountfloat<0.0f, 1.0f>0.5fLowest acceptable fraction of pixels meeting the criteria. Default value: 0.5f.
inMaxAmountfloat<0.0f, 1.0f>1.0fHighest acceptable fraction of pixels meeting the criteria. Default value: 1.0f.
outIsPresentboolFlag indicating whether the object is present or not.
outAmountAvlNet.NullableValue<float>Fraction of pixels meeting the criteria. Can be null to skip this parameter calculation.
outForegroundAvlNet.NullableRef<AvlNet.Region>Region of pixels meeting the criteria. Can be null to skip this parameter calculation.
outAlignedRoiAvlNet.NullableRef<AvlNet.ShapeRegion>Input ROI after transformation (in the image coordinates). Can be null to skip this parameter calculation.
