Abstract: The quality of texture synthesized by Wang Tiles texture synthesis algorithm depends on how to select image patches which are used to construct Wang Tiles from a sample texture.To address this problem，PSO based Wang Tiles texture synthesis algorithm is presented in this paper.This method searches and selects image patches which have minor error between patch boundaries by particle swarm optimization.And these sample patches are used to construct Wang Tiles which then are synthesized by Wang Tiles texture synthesis algorithm.Experiment shows that this method can produce textures which have less seam and better quality than the textures synthesized by randomly chosen image patches.
