A computational methodology for the creation of photorealistic mosaic using breccia tiles
A comparison based tile classification technique has been developed and applied computationally in order to compile a mosaic, which constituting tiles emplaced as to form a particular figure. The mosaics are generated using the surficial shapes of the tiles. Unlike the conventional mosaic tiling process, geometric properties of the tiles do not have any role for the proposed methodology. Therefore, square breccia rock tiles, having variable surface appearances, have been used by processing with the developed algorithm and lined up as to form targeted sample images. The technique showed satisfactory results even with a limited number of tiles in the database. The compilation of the mosaic with the proposed methodology is a very fast and cheap process, which makes it ideal to follow the different requirements of the individual customers and eliminates skilled workforce in the production. Since the mosaic contains different ratios of breccia tiles, having variable surface appearances, the gap between the market prices of the tile groups has been eliminated and an extra value to the final product has been added by attributing an artistic value. The technique offers practically no size limitation for a mosaic, which makes it suitable for large coverings such as ones in museums, lobbies and even for open spaces. The methodology presented in this study allows creating photorealistic mosaics having higher engineering properties
