Abstract :
We describe a new form of energy functional for the modelling and identification of regions in images. The energy is defined on the space of boundaries in the image domain, and can incorporate very general combinations of modelling information both from the boundary (intensity gradients,ldots), em and from the interior of the region (texture, homogeneity,ldots). We describe two polynomial-time digraph algorithms for finding the em global minima of this energy. One of the algorithms is completely general, minimizing the functional for any choice of modelling information. It runs in a few seconds on a 256 times 256 image. The other algorithm applies to a subclass of functionals, but has the advantage of being extremely parallelizable. Neither algorithm requires initialization. |

Abstract :
We propose a new form of energy functional for the segmentation
of regions in images, and an efficient method for
finding its global optima. The energy can have contributions
from both the region and its boundary, thus combining
the best features of region- and boundary-based approaches
to segmentation. By transforming the region energy
into a boundary energy, we can treat both contributions
on an equal footing, and solve the global optimization
problem as a minimum mean weight cycle problem on
a directed graph. The simple, polynomial-time algorithm
requires no initialization and is highly parallelizable. |
