A new method of texture synthesis based on gradient structure information searches along a spiral path

Most of the existing texture synthesis algorithms were proposed in the pursuit of the better synthesis quality or quick synthesis speed, but they could not satisfy requirements at the same time. In this paper, a new texture synthesis algorithm is presented. It adopts the color and the gradient as the similarity measurement of between the two matching patch, which improves their similarity extent. Moreover, a spiral-path searching method is used to search the best texture matching patches and the synthesis time can be decreased dramatically. The experiment results show that not only the synthesis speed is rapider t in great degree, but also the synthesis quality is improved.
