Since phase derivative maps obtained with this measurement technique can be approximated by their actual counterparts convolved by the envelope of the kernel used to extract phases and phase derivatives, non-blind restoration techniques can be used to perform deconvolution. Six deconvolution techniques are compared here in order to restore a synthetic phase derivative map. Obtained results are analyzed and discussed. %G English %2 https://inria.hal.science/hal-00830091/document %2 https://inria.hal.science/hal-00830091/file/SEM2013_GSBM.pdf %L hal-00830091 %U https://inria.hal.science/hal-00830091 %~ UNIV-BREST %~ ENSTA-BRETAGNE %~ PRES_CLERMONT %~ CNRS %~ INRIA %~ UNIV-BPCLERMONT %~ IRSTEA %~ ENSTA-BRETAGNE-LBMS %~ INRIA_TEST %~ INRIA-LORRAINE %~ LORIA2 %~ INRIA-NANCY-GRAND-EST %~ INSTITUT_PASCAL %~ TESTALAIN1 %~ ENIB %~ UNIV-LORRAINE %~ INRIA2 %~ LORIA-ALGO-TEST5 %~ LORIA %~ LORIA-ALGO %~ AGREENIUM %~ NANCY-2014 %~ INRAE %~ MATHNUM
