一种新的纹理合成算法

现有纹理合成算法并不能保证合成物体的完整性,也不能使其分布与样本纹理保持一致。提出了一种分层纹理合成算法。首先,采用归一化图像分割算法提取样本纹理中的视觉显著性前景物体,继而采用图像修复算法修复背景,然后统计前景物体在样本纹理中的分布共生矩阵,以此作为约束,在背景图像上确定前景物体的分布位置。实验结果表明,不仅可以对前景物体独立进行各种变换,得到任意分布的合成纹理,而且可以保证前景物体的完整性。

A Novel Layered Texture Synthesis Algorithm

Current texture synthesis algorithms can neither preserve the integrity of the salient object,nor keep the same distribution of the salient object in the synthesized textures as that in the source texture.A novel layered texture synthesis algorithm was proposed.Firstly,the salient objects were extracted by adopting the normalized cut image segmentation method.Then an image imprinting algorithm was applied to fill the holes caused by salient object extraction in the background to generate a completed background sample,with which we can synthesis the full background image of the target texture.The experimental result shows that this algorithm can not only get the distribution of the salient object in the synthesized textures but also preserve the integrity of the salient object.
