Paintings, frescoes, antique photographic prints, incunabula, old books, handwritten
documents, sculptures, ceramic fragments, and other ancient manufacts constitute the …

This article surveys recent advances in the equivariant approach to the method of moving
frames, concentrating on finite-dimensional Lie group actions. A sampling from the many …

In this article, we discuss the development of automatic artifact reconstruction systems
capable of coping with the realities of real-world geometric puzzles that anthropologists and …

The puzzle assembly problem has many application areas such as restoration and
reconstruction of archeological findings, repairing of broken objects, solving jigsaw type …

The task of assembling fragments in a puzzle-like manner into a composite picture plays a
significant role in the field of archaeology as it supports researchers in their attempt to …

We present a method for automatically solving apictorial jigsaw puzzles that is based on an
extension of the method of differential invariant signatures. Our algorithms are designed to …

We present a novel 3D reassembly method for fragmented, thin objects with unknown
geometry. Unlike past methods, we do not make any restrictive assumptions about the …

In this paper, we present an effective algorithm for reassembling three-dimensional
apictorial jigsaw puzzles obtained by dividing a curved surface into a finite number of …

A jigsaw puzzle solver reconstructs the original image from a given collection of non-
overlapping image fragments using their color and shape information. In this paper we …

Archaeology is a quintessentially “visual” discipline, because visual perception makes us
aware of fundamental properties of objects and allows us to discover how objects were …
