CheckPresence_PixelAmount_Deprecated

Basic

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.
Name Type Range Description
Input value inImage Image Input image
Input value inRoi ShapeRegionDeprecated Location at which object presence is being checked
Input value inRoiAlignment CoordinateSystem2D* Adjusts the region of interest to the position of the inspected object
Input value inColorModel HSxColorModel Selected color model
Input value inBeginHue Integer 0 - 255 Begin of the range of acceptable hue
Input value inEndHue Integer 0 - 255 End of the range of acceptable hue
Input value inMinSaturation Integer 0 - 255 Lowest acceptable saturation
Input value inMaxSaturation Integer* 0 - 255 Highest acceptable saturation
Input value inMinBrightness Real* 0.0 - Lowest acceptable brightness
Input value inMaxBrightness Real* 0.0 - Highest acceptable brightness
Input value inMinAmount Real 0.0 - 1.0 Lowest acceptable fraction of pixels meeting the criteria
Input value inMaxAmount Real 0.0 - 1.0 Highest acceptable fraction of pixels meeting the criteria
Output value outIsPresent Bool Flag indicating whether the object is present or not
Output value outAmount Real Fraction of pixels meeting the criteria
Output value outForeground Region Region of pixels meeting the criteria
Output value outAlignedRoi ShapeRegionDeprecated Input ROI after transformation (in the image coordinates)
Diagnostic input 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.
