  In digital holographic microscopy (DHM),the reconstructed phase distribution is often wrapped into the range (-π,π] when the optical path difference(OPD) introduced by the specimen is larger than the illumination wavelength.Therefore,phase unwrapping operations are needed to retrieve the continu-ous phase distribution.Among all algorithms,the quality-guided (QG) algorithms have a virtue of highly accurate performance for complex geometric sur-faces,but it is limited by computational burden and speed.
