A hole-filling algorithm with parameter estimation for morphological reconstruction of binary images

A new hole-filling method for morphological image reconstruction is proposed in this article. The approach is based on a combination of methods of contour analysis and morphological image processing. For the hole parameters to be estimated, they are described analytically as contours. Then, parameters of the contours, namely the area or the length, are estimated, followed by the decision as to the filling of the contour-bounded hole.
