Gaussian convolution filter.

#include <image_convolve.hpp>

Inheritance diagram for gaussian:

Public Member Functions
	gaussian (double sigma, int mode, image *L)
	Convolve image L using a Gaussian kernel with standard deviation sigma. Mode gives the wrapping mode. The true radius of the kernel is 3 sigma, rounded up.
virtual void	tweak (int a, int v)
	Tweak image parameter a, changing the value by a factor of v.
virtual double	kernel (int y, int x) const
virtual void	doc (std::ostream &out) const
	Produce a string documenting the function of this object.
Public Member Functions inherited from convolve
	convolve (int yradius, int xradius, int mode, image *L)
	Convolve image L using a kernel of the given yradius and xradius. The kernel is expected to be supplied by a subclass.
virtual double	get (int i, int j, int k) const
	Return the value of the sample at row i, column j, channel k.
Public Member Functions inherited from image
	image (image *L=0, image *R=0)
	Create a new image object with left child L and right child R. The parents of L and R are set to this.
virtual	~image ()
	Finalize this image object by deleting any children.
virtual int	get_height () const
	Return the height of this image.
virtual int	get_width () const
	Return the height of this image.
virtual int	get_depth () const
	Return the depth of this image.
image *	getL ()
	Return the left child.
image *	getR ()
	Return the right child.
image *	getP ()
	Return the parent.
virtual void	process ()
	Process all samples of both children.
