Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Decrease in number of calculations in systems of recognition of images N.F. KOVTONYUK, V.V. SMIRNOV In article the condition of a problem of decrease in number of calculations in systems of recognition of images is analyzed. For achievement of this purpose it is offered to use Johnson’s created on the basis of visual recognition of objects by the person operator of optoelectronic station the criterion. According to this criterion, for recognition of images it is possible to be limited to the spatial frequencies taken to a certain threshold, with rejection of higher spatial frequencies. Keywords: Johnson’s criterion, visual recognition, optical mira, critical size, spatial frequencies, reference images. Contacts: E-mail: info@cniikometa.ru Pp. 01-04.
