Meghini C. Logical image modelling and retrieval. In: Computer Journal, vol. 39 (3) pp. 173 - 183. ACM New York, NY, USA, 1996.
A logical model of images is presented, as a theoretical foundation of information svstems allowinz the retrieval of images on the basis of their form (typically via visual queries) and contento The proposed model offers a multiple representation of images, extendžug along three dimensions: form, content and abstraction. At each dirnension, a first-order Iogic is postulated as a representation and reasoning tool, and one specifžc logžc is introduced for the first of these dimensions the one dealina with the form of images. A query on images is modelled along the same three dimensions and by means of the same logžcs. This allows us to model the image retrieval process by the relation of c1assical logical implication, Le. an image is retrieved if it logicalžy implžes the' query.
