FIELD: computer engineering. SUBSTANCE: method includes display of video frame with at least one visual object on monitor screen and separation of video frame with image of at least one visual object into X Y cells. Method provides for intraframe encoding by separating characteristic cells aligned with visual object outline in which visual object outline suffers change of shape. Change in outline between characteristic cells is approximated by mathematical expressions between checkpoints. Local XT and YT coordinate system is inputted and after intraframe encoding it is stored in checkpoint data array card. EFFECT: reduced memory capacity required to store and process visual object coordinates. 16 cl, 22 dwg, 2 tbl
