inlinestatic

Check whether the object is present inside an image, analyzing the amount of edges found in the specified region.

Parameters

inImage	Input image.
inRoi	Where to check for the object.
inRoiAlignment	Region of interest alignment.
inGradientMethod	Method used for gradients' computation.
inMagnitudeMeasure	Measure used for gradients' magnitude.
inGradientScale	Scale for the resulting gradients' magnitude.
inMinMagnitude	Minimum acceptable magnitude value.
inMinAmount	Minimum acceptable fraction of pixels meeting the edge criteria.
inMaxAmount	Maximum acceptable fraction of pixels meeting the edge criteria.
outAmount	Fraction of pixels meeting the edge criteria.
outForeground	Region of pixels meeting the edge criteria.

		ShapeRegion	inRoi,
		Optional< UCS2D >	inRoiAlignment = null,
		HSxModel	inHSxModel = HSxModel::HSV,

		Optional< Region >	outForeground = null,
		Optional< ShapeRegion >	outAlignedRoi = null )

inlinestatic

Check whether the object is present inside an image, based on the amount of pixels that satisfy the color criteria.

If the input image has 3 channels (RGB), the image is converted to the specified HSx model and all 3 pixels' components are compared with hue, saturation and brightness values. Otherwise, if the input consists in a grayscale image, the first (and only) channel values are compared with the brightness range.

Parameters

inImage	Input image.
inRoi	Where to check for the object.
inRoiAlignment	Region of interest alignment.
inHSxModel	HSx color model.
inMinHue	Minimum acceptable hue value.
inMaxHue	Maximum acceptable hue value.
inMinSaturation	Minimum acceptable saturation value.
inMaxSaturation	Maximum acceptable saturation value. If Null, the value is set to the highest value (255).
inMinBrightness	Minimum acceptable brightness value. If Null, the value is set to the lowest value (0).
inMaxBrightness	Maximum acceptable brightness value. If Null, the value is set to the highest value (255).
inMinAmount	Minimum acceptable fraction of pixels meeting the color criteria.
inMaxAmount	Maximum acceptable fraction of pixels meeting the color criteria.
outAmount	Fraction of pixels meeting the color criteria.
outForeground	Region of pixels meeting the color criteria.
outAlignedRoi	Aligned region of interest.

Returns: True if the object is present, false otherwise.

◆ IsObjectPresent() [3/3]

bool oevislib_net.ComputerVision.ImageAnalysis.ImageAnalysis.IsObjectPresent	(	Image	inImage,
		ShapeRegion	inRoi,
		Optional< UCS2D >	inRoiAlignment = null,
		Optional< float >	inMinIntensity = null,
		Optional< float >	inMaxIntensity = null,
		float	inMinContrast = 0::2f,
		Optional< float >	inMaxContrast = null,
		Optional< float >	outIntensity = null,
		Optional< float >	outContrast = null,
		Optional< ShapeRegion >	outAlignedRoi = null )

inlinestatic

Parameters

inImage	Input image.
inRoi	Where to check for the object.

inMinIntensity	Minimum acceptable value for mean pixel intensity. If Null, the lowest possible value is considered.
inMaxIntensity	Maximum acceptable value for mean pixel intensity. If Null, the highest possible value is considered.
inMinContrast	Minimum acceptable value for the standard deviation of the pixel values.
inMaxContrast	Maximum acceptable value for the standard deviation of the pixel values. If Null, the highest possible value is considered.
outIntensity	Average pixel value.
outContrast	Standard deviation of the pixel values.
outAlignedRoi	Aligned region of interest.

Returns: True if the object is present, false otherwise.
