Image sharpening.

Function Documentation

unsharpMask() [1/4]

void vp::unsharpMask	(	const vpImage< unsigned char > &	I1,
		vpImage< unsigned char > &	I2,
		unsigned int	size = 7,
		double	weight = 0.6
	)

Sharpen a grayscale image using the unsharp mask technique.

Parameters

I1	: The first input grayscale image.
I2	: The second output grayscale image.
size	: Size (must be odd) of the Gaussian blur kernel.
weight	: Weight (between [0 - 1[) for the sharpening process.
