拼图是使用不同形式的素材进行组装的合成艺术.文中介绍了一种崭新的拼图创作方法,通过挑选主题相关的网络图像的前景抠图来表现一幅输入图像,能够生成奇异的具有阿奇姆博多风格的拼图.鉴于网络图像数据的海量规模,总能够找到合适的前景抠图来匹配输入图像的各个分割部分;通过将挑选的前景抠图按照一定的规则进行组装,使其在整体上可以从形状和颜色表现输入图像,而在局部每个前景抠图仍然可以辨识.实验结果和用户体验表明,采用文中方法可以有效地生成具有娱乐性的阿奇姆博多拼图.

英文摘要：

Collage is a composite artwork made from assemblage of different material forms.In this work,we present a novel approach for creating a fantastic collage artform,namely Arcimboldo-like collage,which represents an input image with multiple thematically-related cutouts from the filtered Internet images.Due to the massive data of Internet images,competent image cutouts can almost always be discovered to match the segmented components of the input image.The selected cutouts are purposefully arranged such that as a whole assembly,they can represent the input image with disguise in both shape and color;but separately,individual cutout is still recognizable as its own being.Experimental results and user study show that our algorithm can effectively produce the entertaining Arcimboldo-like collages.
