The quality of the recognition system is largely determined by what the signs of her images are considered. The purpose of research is development of a way of the substantial description and comparison of lines of outline drawings. It is offered to present a line form in the form of a linguistic variable. Experiments on comparison of contours of machine-building details and objects of satellite images which show high efficiency of the offered approach in respect of quality and speed are given.
