在本文中，我们提出了一种新的基于样本的技术，结合基于补丁和统计方法的两个纹理之间的插值。受纹理作为一种局部现象的概念的启发，我们在基于补丁的纹理合成之前扭曲和混合小图像邻域。此外，内插和加强特征图像统计忠实地处理高频细节。我们能够创建中间纹理以及连续过渡。与之前在整个输入样本图像上计算全局变形变换的技术相比，我们的本地化和基于补丁的方法允许我们成功地在特征拓扑存在相当大差异的纹理之间进行插值，其中不存在平滑的全局变形场。
In this paper, we present a novel exemplar‐based technique for the interpolation between two textures that combines patch‐based and statistical approaches. Motivated by the notion of texture as a largely local phenomenon, we warp and blend small image neighborhoods prior to patch‐based texture synthesis. In addition, interpolating and enforcing characteristic image statistics faithfully handles high frequency detail. We are able to create both intermediate textures as well as continuous transitions. In contrast to previous techniques computing a global morphing transformation on the entire input exemplar images, our localized and patch‐based approach allows us to successfully interpolate between textures with considerable differences in feature topology for which no smooth global warping field exists.
