We present a method for the automatic assembly of apictorial jigsaw puzzles. This method relies on integral area invariants for shape matching and an optimization process to aggregate shape matches into a final puzzle assembly. Assumptions about individual piece shape or arrangement are not necessary. We illustrate our method by solving example puzzles of various shapes and sizes.

积分不变量在图形拼图拼图中的应用

我们提出了一种自动组装图形拼图的方法。该方法依赖于用于形状匹配的积分区域不变量和将形状匹配聚合到最终拼图组件中的优化过程。不需要对单个零件的形状或排列进行假设。我们通过解决各种形状和大小的示例谜题来说明我们的方法。
