Function Documentation

◆ fillHoles()

void vp::fillHoles ( vpImage< unsigned char > &  I)

Fill the holes in a binary image.

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

◆ reconstruct()

void vp::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 ) $

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