The use of Prolog language family for image recognition

The paper is devoted to the investigation of Prolog language family possibility for its use in the solving of the display image recognition. Difficulties appeared in the Prolog implementation of the approach are marked out. It is shown the way in which the number of deduction algorithm steps allows to overcome the appeared difficulties. Examples of the Prolog programs implementation to the separation of an etalon image from a complex one are done. Peculiarities of the use of different recognizable image formats are analized.
