Abstract:
1. A visual-guidance-information generation system for generating visual-guidance information indicating how the line of sight is guided through the segmented multiple partial regions of an image, the system comprising: a saliency-feature acquisition device to acquire saliency features indicative of a degree of focusing attention on the partial regions; a positional-information acquisition device to acquire positional information indicative of a position of the partial regions in the image; and a visual-guidance-information generation device to generate the visual-guidance information based on the saliency features acquired by the saliency-feature acquisition device and the positional information acquired by the positional-information acquisition device; and a reference-point detection device to detect reference points of the partial regions from the visual-guidance feature space in which the saliency features and factors of the positional information are plotted in different axes; and a inter-reference-point-distance calculation device to calculate distances among the reference points detected by the reference-point detection device, the visual-guidance-information generation device generating the visual-guidance information based on the inter-reference-point distances calculated by the inter-reference-point-distance calculation device, the visual-guidance-information generation device generating visual-guidance information indicative of a visual guidance path that passes through the partial regions in sequence based on the inter-reference-point distances calculated by the inter-reference-point-distance calculation device, and the visual-guidance-information generation device forming the visual guidance path that passes through the partial regions in sequence, with a prescribed starting-point region of the multiple partial regions as a starting point and with a partial region having the shortest inter-reference-point distance from the preceding partial region as the following partial region, and generating visual-guidance information indicative of the formed visual guidance path.
