Summary: This paper introduces a new kind of mosaic, called the Decorative PixMosaic, where photo tiles of square shapes are used to compose the final image. We can express the resulting image with a similar color distribution of input images from small photo tiles. Based on an input image, user-selected edge features and a wide range of photo tiles, the method can both reproduce the image’s textures and emphasize the selected edges by placing tiles that follow the edges. The voronoi site is situated in the center point of the tile using the Centroidal Voronoi Diagram for equally maintaining the distance among the tiles. To express the edges using tiles on the voronoi site as the center point, tiles do not cross image edges and are drawn up as following edge’s direction. We use a distribution photo with similar color selected from the photo database. It is important to search for a visually similar photo. Hence we must have a large number of photo tiles.
