◆ computeMaskSize()

int Freestyle::GaussianFilter::computeMaskSize ( float sigma )

◆ getSmoothedPixel()

template<class Map >

float Freestyle::GaussianFilter::getSmoothedPixel	(	Map *	map,
		int	x,
		int	y )

Returns the value for pixel x,y of image "map" after a gaussian blur, made using the sigma value. The sigma value determines the mask size (~ 2 x sigma).

Parameters

map	The image we wish to work on. The Map template must implement the following methods: float pixel(uint x, uint y) const; uint width() const; uint height() const;
x	The abscissa of the pixel where we want to evaluate the gaussian blur.
y	The ordinate of the pixel where we want to evaluate the gaussian blur.
