For 2D-like pictures (legs of fan pictured from bottom), the fix might be possible. For 3D (propeller blades with every blade having a right and a left face), it will be not.

The software will need to choose the final position of blades in the rendered picture. There is no ideal position since the blades have been moving throughout the scan time. Whichever position we decide, there will be information missing for one/more blade. Say, left face of blade no. X needs to be rendered but the camera only captured its right face. May be assuming that all blades have same shape and information of one blade can be used in rendering other blade will fix the problem.

Also missing background will have to be reconstructed. That's another issue.
