摘要

本文介绍了一种新的拼接方法——拼图图像拼接(Jigsaw Image mosaic, JIM),它使用任意形状的图像块组成最终的图像。拼图图像马赛克的生成解决了以下问题:给定一个任意形状的容器图像和一组任意形状的图像瓦片,用与输入集中容器颜色相似的瓦片尽可能紧凑地填充容器,同时选择性地稍微变形它们,以获得更令人愉悦的视觉效果。我们通过将马赛克定义为最小化马赛克能量函数的瓷砖配置来解决这个问题。我们介绍了一个通用的基于能量的镶嵌问题框架,扩展了现有的一些算法,如Photomosaics和simulation Decorative Mosaics。我们还提出了一种快速算法,在可接受的计算成本下解决拼接问题。我们通过将我们的方法应用于各种容器图像和图块来演示它的用法。

Jigsaw image mosaics
This paper introduces a new kind of mosaic, called Jigsaw Image Mosaic (JIM), where image tiles of arbitrary shape are used to compose the final picture. The generation of a Jigsaw Image Mosaic is a solution to the following problem: given an arbitrarily-shaped container image and a set of arbitrarily-shaped image tiles, fill the container as compactly as possible with tiles of similar color to the container taken from the input set while optionally deforming them slightly to achieve a more visually-pleasing effect. We approach the problem by defining a mosaic as the tile configuration that minimizes a mosaicing energy function. We introduce a general energy-based framework for mosaicing problems that extends some of the existing algorithms such as Photomosaics and Simulated Decorative Mosaics. We also present a fast algorithm to solve the mosaicing problem at an acceptable computational cost. We demonstrate the use of our method by applying it to a wide range of container images and tiles.
