Robust high breakdown point location estimators are
employed to analyze image stacks under the piecewise constant
image structure model. To reduce the effect of bias along the Z axis,
the class parameters are extracted using three consecutive slices.
The segmentation algorithm first determines the most reliable seed
regions which are then
used in a region-growing procedure supported by local evidence.
The robustness and stability of the proposed technique is shown
with both synthetic and real data, the latter consisting of one
MRI and one confocal microscopy set.
The performance of the algorithm is consistent with the
ground truth obtained with manual segmentation by physicians.
