Abstract
This paper discusses the process of interpreting scenes with the image of a human face, subjected to processing with spatial-frequency filters that simulate the characteristics of the receptive fields of the neurons of the primary visual cortex. A technique was used that makes it possible to give a quantitative evaluation of the interpretation of an image while carrying out tasks of identifying a period of emotional stress and the age-related features of the person. It was shown that, besides the horizontal components of the spatial-frequency spectrum, a substantial role is played in the process of interpreting images of faces by the diagonal components. Even though the visual system is less sensitive to the diagonal components than to the horizontal ones, the information contained in them makes it possible not only to distinguish age-related features, but also to give the supplementary information needed to identify an unfamiliar person when encountering that person again.
