 Abstract: In this paper, a new scheme for extracting a closed contour of some object given one initial point in the interior of the object is proposed.

The principal domain of application is the analysis of MRI images of the human brain. The scenario envisaged here is the following. The user (a medical doctor for instance) ”clicks” on some area of interest in the MRI image, and the algorithm then automatically extracts the object containing the pixel clicked upon, so that the object's shape parameters and its size can be computed.

The assumption underlying the approach is that the contour of the object can at least be partially extracted by some standard edge extraction procedure. The purpose of our algorithm is then to connect the edge fragments in a meaningful manner, so that a closed contour of the object results. The principal idea of the approach is to pack the interior of the object with maximal discs. Special provisions are made to prevent the discs from squeezing through gaps in the boundary.
