METHOD OF DETECTION AND IDENTIFICATION OF PATTERNS AND ORNAMENTS, AND INTELLIGENT-INFORMATION SYSTEM FOR ITS IMPLEMENTATION

摘要

The invention relates to information technologies and concerns systems of detection and identification of patterns and ornaments in arts and crafts articles, and in particular hand-made carpet articles. The invention essence is determination of informative parameters for comparison with reference parameters, in form of colour pixels distribution density diagrams, determination of the presence and type of symmetry, and calculation of the centre of gravity of the article. Graphical images of the patterns and ornaments are decomposed to elementary components along the contours formed at borders of pixels of different colours. In this process, depending on the colour pixels in the pattern or ornament, the colour image is changed to a black-and-white one so that if margins are black, then the contours are white, and vice versa. Decomposition in accordance with the developed algorithms is performed successively: from a complex image to simple shapes, then in colour components and main patterns. The proposed method of detection and identification of patterns and ornaments in arts and crafts articles is an intelligent-information expert system, and allows not only keeping a register of valuable arts and crafts articles, in particular, hand-made carpets, but also carrying out their identification and detection and restoration of the articles on the basis of preserved fragments, and also formation of new patterns, ornaments and carpets.
