int LEDDetector::Compute	(	const BIAS::Image< unsigned char > &	image,
		std::vector< BIAS::Vector3< double > > &	results
	)

Detect LED spots in image.

Parameters

[in]	image	RGB or gray image to detect LED spots in.
	in/out]	results Returns LED spot positions in current image. Parameters of 3d vectors are (x, y, val) where val is brightness. Can be also used as input parameter to specify LED spots positions in last image to use "recycling" mode.

Returns: Returns <0 in case of errors, >= 0 otherwise.

Return attributes of detected LED spots.

Parameters

[out]	minX	Returns min. x coordinate for each detected LED spot
[out]	maxX	Returns max. x coordinate for each detected LED spot
[out]	maxValues	Returns max. gray value for each detected LED spot
