Regularization in overlapping partitions. Example of partition of a full stack into two disjoint substacks A and B and two overlapping substacks A’ and B’. Once the regularization has been performed in A’, only voxels belonging to A are updated. Then, regularization is performed in B’ and only voxels belonging to B are updated. This procedure prevents the appearance of regularization artifacts in the boundary between A and B
