Function Documentation

unsharpMask() [1/4]

VISP_EXPORT void VISP_NAMESPACE_NAME::unsharpMask	(	const VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &	I,
		VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &	Ires,
		float	sigma,
		double	weight = 0.6
	)

Sharpen a grayscale image using the unsharp mask technique.

Parameters

I	: The input grayscale image.
Ires	: The output grayscale image.
sigma	: Standard deviation for Gaussian kernel.
weight	: Weight (between [0 - 1[) for the sharpening process.

unsharpMask() [2/4]

		float	sigma,
		double	weight = 0.6
	)

Sharpen a color image using the unsharp mask technique.

Parameters

I	: The input color image.
Ires	: The output color image.
sigma	: Standard deviation for Gaussian kernel.
weight	: Weight (between [0 - 1[) for the sharpening process.
