基于Image Quilting算法的纹理合成

Texture Synthesis and Texture Transfer Based on Image Quilting

基于样图的纹理合成方法是继纹理映射、过程纹理合成方法后发展起来的纹理拼接技术,用于解决传统方法中出现的缝隙、扭曲、变形和参数调整等问题。Image Quilting算法是简单易行的接缝消除方法,采用Image Quilting算法合成纹理并生成Wang Tile集,继而拼接大图像。实验表明,Image Quilting算法能够较好地保持纹理特征的连续性,但在接缝处可能破坏纹元特征。

Sample-based texture synthesis is a new texture tiling technique developed after the texture mapping and procedural texture synthesis.It can efficiently avoid noticeable seams between texture patches,minimize the stretch and distortion of the pattern when tiling a texture on surfaces,get rid of complicated parameters adjustment.Based on Image Quilting—a simple effective seam removing method,an implement of texture synthesis and Wang tile sets generation is given in this paper.It was tested by experiment that features of texton across the seam may be destroyed during synthesis.
