Detailed Description

A class that does space-variant processing with progressive blurring.

A Gaussian blur is applied throughout the image, with small blur radius near the foveation origin, which increases as we go further into the periphery. This causes the image to appear sharp near the origin while blurry toward the outer edges.

Testing has revealed that BlurFoveator is not as efficient as PyrFoveator or LPTFoveator but can still achieve the desired result.

Constructor & Destructor Documentation

BlurFoveator::BlurFoveator	(	const Image< PixRGB< byte > > &	img,
		int	filterSize
	)

Construct a BlurFoveator for an image.

This constructor will create a BlurFoveator that handles img and all other images of the same dimensions.

Parameters:

	img	image to be foveated
	filterSize	size of blur filter to be applied

Member Function Documentation

Image< PixRGB< byte > > BlurFoveator::foveate	(	const Image< PixRGB< byte > > &	img,
		int	filterSize,
		int	x,
		int	y
	)			[static]

Perform one blur foveation without a BlurFoveator.

This function is for foveating ONE image with a call such as BlurFoveator::foveate(). It is not optimized for foveating multiple images.

Parameters:

	img	image to be foveated
	filterSize	size of blur filter to be applied
	x	horizontal coordinate of origin
	y	vertical coordinate of origin
