Abstract

Traditional 2D texture synthesis methods mainly focus on seamlessly generating a big size texture, with coherent texture direction and homogeneous texture scale, from an input sample. This paper presents a method of synthesizing texture with variational direction and scale on arbitrary planar region. The user first decomposes the interest region into a set of triangles, on which a vector field is subsequently specified for controlling the direction and scale of the synthesized texture. The variational texture direction and scale are achieved by mapping a suitable texture patch found in the sample via matching a check-mask, which is rotated and zoomed according to the vector field in advance. To account for the texture discontinuity induced by not well matching or different texture directions/scales between adjacent triangles, a feature based boundary optimization technique is further developed. Experimental results show the satisfactory synthesis results.
