Abstract: Patch-based texture synthesis builds a texture by joining together texture blocks taken from the original texture sample.Its basic idea is to select a group of blocks from the sample,and then joint the blocks in some way to get the output texture.We proposed D-Tile for texture synthesis based on artificial bee colony.Firstly,the idea of artificial bee colony algorithm is introduced to select four square texture blocks which have smaller differences of pixels at the boundary.Texture blocks with smaller differences of pixels can reduce the obvious level of the seams in D-Tile,and choosing square texture makes the texture sample’s corner information can be utilized.Secondly,the four blocks are tiled with some overlaps,the diagonal is connected respectively,and the diamond texture patch in the center is taken as D-Tile framework.This selection of framework can avoid the corner problem when tiling the D-Tiles.Lastly,the D-Tile is used to synthesis texture according to the principle of border color matching.The experimental result shows that this algorithm can achieve a good visual effect of various type of texture.
