Abstract. The psychophysiological state of a person when observing visual scenes depends, among other things, on the visual complexity of the images. Images of laser graphics are used to create visual content for the rooms of psychological relief. To increase the effectiveness of such rooms, it is necessary to be able to assess the visual complexity of the images of the laser graphics, as well as its range, in which the images will have a relaxing effect. For these purposes, a method for determining the degree of self-similarity of images based on a pyramid of oriented gradients is proposed.
Keywords: self-similarity, histogram of oriented gradients, fractal dimension, image outline, psychoemotional perception, abstract lase raster image, psychophysiological impact
