嵌套图像是一种艺术表现形式，其中一个或多个次要人物一个接一个地嵌入初级人物中。初级人物的轮廓，特别是其内孔的轮廓，被用来描绘次级人物。次要人物完全在原形内部，利用原形的一些内孔作为其自身的一部分，从而产生艺术效果。在这里，我们介绍了一个创建此类图像的系统。它依靠人的感知经验来最小化嵌入的内部图形和原始外部图形之间的差异。我们的系统检测要嵌套的图形的封闭外轮廓，然后通过基于轮廓距离的能量优化，在外部图形中找到一个位置来嵌入它，并进行适当的变换。变形是通过迭代方法完成的，该方法将内部图形的对应轮廓和外部图形的孔扭曲到适当的位置。我们展示了由我们的
A nested image is a form of artistic expression in which one or more secondary figures are embedded within a primary figure one by one. Contours of the primary figure, especially the contours of its inner holes, are used to portray a secondary figure. The secondary figure is totally inside the primary figure, and it would use some inner holes of primary figure as part of itself, which would produce an artistic effect. Here, we present a system for creating such images. It relies on the experience of human perception to minimize the difference between embedded inner figure and primary outer figure. Our system detects the enclosed outer contour of the figure to be nested, and then finds a place in the outer figure to embed it, together with a suitable transformation for doing so, by optimizing an energy based on the distance of contours. Morphing is done by an iterative approach, which warps the corresponding contours of the inner figure and the holes of the outer figure to an appropriate position. We show various nested images generated by our
