We consider the apparent contours of the smooth hypersurfaces as the projection data and formulate some sufficient conditions of coincidence of the shapes of two hypersurfaces, if the shapes of their apparent contours on any 2-dimensional plane coincide. We also obtain new results on reconstruction of smooth surfaces from observations of the wavefronts generated by these surfaces. © 1999 IEEE.en10.1109/SMA.1999.749330info:eu-repo/semantics/closedAccessConference Object116120N/A
