Function Documentation

unsharpMask() [1/8]

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

Deprecated:

This function is deprecated. You should rather use unsharpMask() with sigma Gaussian parameter. You can use sigma = 1.0f to have similar results.

Sharpen a grayscale image using the unsharp mask technique.

Parameters

I	: The grayscale image to sharpen.
size	: Size (must be odd) of the Gaussian blur kernel.
weight	: Weight (between [0 - 1[) for the sharpening process.

Examples:

testImgproc.cpp, and tutorial-contrast-sharpening.cpp.
