Phase unwrapping algorithm based on Region Labeling

In the processing of 3D profilometry based on phase,one most important key techniques is get reasonable continuous phase map avoiding an ill-state wrapped phase map effectively. The paper provides a new phase unwrapping algorithm based on region labeling and virtual residuals. The algorithm can obtain an reasonable continuous phase map to overcome the disadvantages of incorrect residuals and cut-lines.
