The jigsaw puzzle assembly problem is significant in that it can be applied to diverse areas such as repair of broken objects , restoration of archaeological findings, molecular docking problem for drug design, etc. This paper describes a new pictorial jigsaw puzzle solver which, in contrast to previous apictorial jigsaw puzzle solvers, uses chromatic information as well as geometric shape. We ...

We explore an opportunity to expand the stylistic variety of handmade and artisanal jigsaw puzzles through the appication of techniques from natural simulation. Typical jigsaw puzzle designs reflect the manufacturing constraints of die-cut, mass-production methods. We generate novel families of puzzle forms by applying a phase field approach to the simulation of dendritic solidification. We ext...

In this paper, we consider the square jigsaw puzzle problem in which one is required to reassemble the complete image from a number of unordered square puzzle pieces. Here we focus on the special case where both location and orientation of each piece are unknown. We propose a new automatic solver for such problem without assuming prior knowledge about the original image or its dimensions. We us...

Sex differences are consistently reported in different visuospatial tasks with men usually performing better in mental rotation tests while women are better on tests for memory of object locations. In the present study, we investigated sex differences in solving jigsaw puzzles in children. In total 22 boys and 24 girls were tested using custom build tablet application representing a jigsaw puzz...

This paper investigates the engaging concept of virtual 3D jigsaw puzzles to foster the understanding of spatial relations within technical or biological systems by means of virtual models. Employing an application in anatomy education, it answers the question: How does guided spatial exploration, arising while composing a 3D jigsaw, affect the acquisition of spatial-functional understanding in...

Most jigsaw puzzles that are available today consist of several 100 pieces of a single image, and can take several hours to solve. This project proposes to solve the puzzle simply by using a picture of all of the pieces, and an image of the final solution.

CROSSWORD PUZZLES, hidden messages, word scrambles, word searches, card games, and “virtual” rats are used to motivate students, enhance their understanding of physiology, and foster logical thinking and problem-solving skills (1, 5–7). Similarly, jigsaw puzzles advance these attributes while also promoting the development of visual-spatial processing skills (9). The process of constructing the...

Some individuals with Prader-Willi syndrome exhibit strengths in solving jigsaw puzzles. We compared visuospatial ability and jigsaw puzzle performance and strategies of 26 persons with Prader-Willi syndrome and 26 MA-matched typically developing controls. Individuals with Prader-Willi syndrome relied on piece shape. Those in the control group used a different, picture-focused strategy. Individ...

Software systems have become increasingly complex over the years. Complexity metrics measures software complexity using real numbers. It is, however, hard to gain insight into different complexities by looking at these numbers. In this paper, we present a software complexity metaphor that uses a jigsaw puzzle. In particular, each component of a software system is modelled as a piece of a jigsaw...
