Function Documentation

fillHoles()

void VISP_NAMESPACE_NAME::fillHoles

(

vpImage< unsigned char > &

I

)

Fill the holes in a binary image.

Parameters

I	: Input binary image (0 means background, 255 means foreground).

Examples

testContours.cpp, and tutorial-count-coins.cpp.

reconstruct()

void VISP_NAMESPACE_NAME::reconstruct	(	const vpImage< unsigned char > &	marker,
		const vpImage< unsigned char > &	mask,
		vpImage< unsigned char > &	h_kp1,
		const vpImageMorphology::vpConnexityType &	connexity = vpImageMorphology::CONNEXITY_4
	)

Perform morphological reconstruction of the image marker under the image mask. Definition from Gleb V. Tcheslavsk: > The morphological reconstruction by dilation of a grayscale image \( g \) by a grayscale marker image \( f \) > is defined as the geodesic dilation of \( f \) with respect to \( g \) repeated (iterated) until stability is reached:

\[ R_{g}^{D} \left ( f \right ) = D_{g}^{\left ( k \right )} \left ( f \right ) \]

with \( k \) such that: \( D_{g}^{\left ( k \right )} \left ( f \right ) = D_{g}^{\left ( k+1 \right )} \left ( f \right ) \)

Parameters

marker	: Grayscale image marker.
mask	: Grayscale image mask.
h_kp1	: Image morphologically reconstructed.
connexity	: Type of connexity.
