摘要
针对Image Quilting纹理合成算法拼贴块时会出现的边界不连续现象,提出一种基于多阶误差曲面的纹理合成改进算法。该算法通过多阶误差曲面来计算最小误差边界分割,从而得到更精确的最佳切割路径;此外在按照最佳切割路径拼贴块后,利用泊松混合(Poisson Blending)来修复边界不连续区域,使得不连续的边界区域能够变得平滑,纹理合成效果更符合视觉要求,并且将改进后的算法扩展到纹理传输的实现。实验结果表明,改进后的算法可以较好地克服Image Quilting算法存在的不足,得到良好的合成结果。
In order to deal with the boundary discontinuities in Image Quilting texture synthesis algorithm,an improved texture synthesis algorithm based on multi-order error surface is proposed.The algorithm calculated the minimum error boundary cut by multi-order error surface to obtain a more accurate optimal cutting path.In addition,after piecing the blocks according to the optimal cutting path,Poisson Blending was used to repair the discontinuous regions of the boundary to make the discontinuous boundary regions smooth,which made the effect of texture synthesis more conform to the requirements of the visual effect.Furthermore,the improved algorithm was extended to the realization of the texture transfer.Experimental results prove that the proposed algorithm can overcome the shortcomings of Image Quilting algorithm and obtain good results.
