Abstract

Selective segmentation is an important application of image processing. In contrast to global segmentation in which all objectsare segmented, selective segmentation is used to isolate specific objects in an image and is of particular interest in medicalimaging—permitting segmentation and review of a single organ. An important consideration is to minimise the amount of userinput to obtain the segmentation; this differs from interactive segmentation in which more user input is allowed than selectivesegmentation. To achieve selection, we propose a selective segmentation model which uses the edge-weighted geodesicdistance from a marker set as a penalty term. It is demonstrated that this edge-weighted geodesic penalty term improveson previous selective penalty terms. A convex formulation of the model is also presented, allowing arbitrary initialisation.It is shown that the proposed model is less parameter dependent and requires less user input than previous models. Furthermodifications are made to the edge-weighted geodesic distance term to ensure segmentation robustness to noise and blur. Wecan show that the overall Euler–Lagrange equation admits a unique viscosity solution. Numerical results show that the resultis robust to user input and permits selective segmentations that are not possible with other models.
