A method and a system for reconstructing obstructed face portions are provided herein. The method may include the following steps: obtaining off-line 3D data, being 3D data of a head of a person not wearing a face-obstructing object, being an object which obstructs a portion of the face of the person; obtaining in real time, real-time 3D data, being 3D data of said head, wherein said person wears said face-obstructing object; applying a 3D transformation to at least a portion of the off-line 3D data, based on the real-time 3D data, to yield reconstructed real time 3D data, being real-time 3D data related to the obstructed face portions; and merging the reconstructed real time 3D data into the real-time 3D data. The system may implement the aforementioned steps over a computer processor.
