CheckPresence_PixelAmount_Deprecated


Header: AVL.h
Namespace: avl
Module: FoundationPro

Verifies object presence by analysing the amount of pixels that meet the specified criteria.

Applications: Quick and easy presence verification, e.g. for missing caps, screws, labels.

	avl::HSxColorModel::Type inColorModel,
	int inBeginHue,
	int inEndHue,
	int inMinSaturation,
	atl::Optional<int> inMaxSaturation,
	atl::Optional<float> inMinBrightness,
	atl::Optional<float> inMaxBrightness,
	float inMinAmount,
	float inMaxAmount,
	bool& outIsPresent,
	atl::Optional<float&> outAmount = atl::NIL,

	avl::Image& diagHsxImage
)

Parameters

Name Type Range Default Description

outIsPresent bool& Flag indicating whether the object is present or not
outAmount Optional<float&> NIL Fraction of pixels meeting the criteria
outForeground Optional<Region&> NIL Region of pixels meeting the criteria
outAlignedRoi Optional<ShapeRegionDeprecated&> NIL Input ROI after transformation (in the image coordinates)
diagHsxImage Image& Image represented in chosen color model

Requirements

For input inImage only pixel formats are supported: 3⨯uint8, 1⨯uint8, 1⨯int8, 1⨯uint16, 1⨯int16, 1⨯int32, 1⨯real.

Read more about pixel formats in Image documentation.

Optional Outputs

The computation of following outputs can be switched off by passing value atl::NIL to these parameters: outAmount, outForeground, outAlignedRoi.
