We present a novel patch-based algorithm for synthesizing a moving 2D texture, i.e. a sequence of frame-coherent 2D textures. In our method, the input are a sample texture and a 2D flow field. We first synthesize a 2D directional texture according to the direction information of the flow field and then let the texture move following the flow. Iteratively, the texture Ti+1 of the (i + 1)-th frame is first obtained by moving forward the texture Ti in a piecewise manner. Then necessary hole-filling and blending is used to make Ti+1 coherent with Ti. In addition, to maintain good visual quality throughout the sequence of textures, best-matching patches from the sample texture are used at selected locations of Ti+1 to prevent cumulative blurring due to blending. Our test examples show that our method is capable of generating high quality moving textures with attractive visual effects that are useful for flow visualization.
