Function Documentation

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

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.
