◆ 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.
