Member Function Documentation

void AprilTags::Gaussian::convolveSymmetricCentered	(	const std::vector< float > &	a,
		unsigned int	aoff,
		unsigned int	alen,
		const std::vector< float > &	f,
		std::vector< float > &	r,
		unsigned int	roff
	)			[static]

Convolve the input 'a' (which begins at offset aoff and is alen elements in length) with the filter 'f'.

The result is deposited in 'r' at offset 'roff'. f.size() should be odd. The output is shifted by -f.size()/2, so that there is no net time delay.

Parameters:

	a	input vector of pixels
	aoff
	alen
	f
	r	the resultant array of pixels
	roff

std::vector< float > AprilTags::Gaussian::makeGaussianFilter	(	float	sigma,
		int	n
	)			[static]

Returns a Gaussian filter of size n.

Parameters:

	sigma	standard deviation of the Gaussian
	n	length of the Gaussian (must be odd)
