	find image moments and return a 5x5 matrix containing the moments. The bglevel parameter is the background grey level that is ignored when find the moment
boost::numeric::ublas::vector< double >	findHuInvariantMoments (const image< unsigned char > imagein, const unsigned char bglevel=0, bool binaryImage=false)
	find the 7 Hu invariant moments and return it as a vector. Note that the vector indices from 0..6, so Hu moment 1 is 0, Hu moment 2 is 1, etc. The bglevel parameter sets the background grey level so that these pixels are ignored in the image.

Member Function Documentation

boost::numeric::ublas::matrix< double > mimas::moments_tool::findMoments	(	const image< unsigned char >	imagein,
		const unsigned char	bglevel = 0,
		bool	binaryImage = false
	)

find image moments and return a 5x5 matrix containing the moments. The bglevel parameter is the background grey level that is ignored when find the moment

boost::numeric::ublas::vector< double > mimas::moments_tool::findHuInvariantMoments	(	const image< unsigned char >	imagein,
		const unsigned char	bglevel = 0,
		bool	binaryImage = false
	)

find the 7 Hu invariant moments and return it as a vector. Note that the vector indices from 0..6, so Hu moment 1 is 0, Hu moment 2 is 1, etc. The bglevel parameter sets the background grey level so that these pixels are ignored in the image.
