Abstract: Highlights•A two-procedure selective segmentation approach: unsupervised then refinement stages.•Procedure II implemented as joint deep variational model or as individual unit.•Mutual benefits achieved by combining variational methods with deep learning.•Our approach doesn’t impose strict requirements on point positions.•Individual module allows unlimited repetition until corrections reach satisfactory level.
