template<class T >

void lowPassPixel	(	Image< T > &	src,
		const int	x,
		const int	y,
		const int	radius
	)			[inline]

Perform a low pass filter about a specific pixel.

Parameters:

	x	The x coord of the pixel
	y	The y coord of the pixel
	radius	The radius of the filter

template<class T >

Image<PixRGB<T> > omniCorrectGen	(	const Image< PixRGB< T > > &	src,
		const int	Rx,
		const int	Ry,
		const int	Xc,
		const int	Yc,
		const int	RA = 0
	)			[inline]

First step of omni directional correction.

Parameters:

	image	The image your are going to process
	Rx	The Radius in X - May be equal to Ry
	Ry	The Radius in Y - May be equal to Rx
	Xc	The center pixel x
	Yc	The center pixel y
	RA	Manual radius adjustment, this is used only for distortion adjustment.

Note:

omniCorrectSp must be used next for full correction unless image is a true pinhole image.

Image<PixRGB<T> > omniCorrectSp	(	const Image< PixRGB< T > > &	src,
		const float	r,
		const float	hh,
		const float	kk,
		const int	Rx,
		const int	Ry,
		const int	Xc,
		const int	Yc
	)			[inline]

Second step of omni-directional correcton.

Values for r,h,k must be obtained via measurement and derived via circular regression (see Mundhenk et al SPIE 2000) Note: run omniCorrectGen first.

Parameters:

	image	The image your are going to process
	r	The radius calculated by circular regression
	hh	The Circle center coord h (i.e. x)
	kk	The Circle center coord k (i.e. y)
	Rx	The Radius in X - May be equal to Ry
	Ry	The Radius in Y - May be equal to Rx
	Xc	The center pixel x
	Yc	The center pixel y
