A shape and image merging technique to solve jigsaw puzzles
This paper proposes an algorithm for solving subsets of typical (canonical) jigsaw puzzles. This algorithm combines shape and image matching with a cyclic ‘‘growth’’ process that tries to place pieces in their correct positions. First, the jigsaw pieces are extracted from the input image. Then, the corner points of the jigsaw pieces are detected. Next, piece classification and recognition are p...
متن کاملNo Easy Puzzles: A Hardness Result for Jigsaw Puzzles
We show that solving jigsaw puzzles requires Θ(n ) edge matching comparisons, making them as hard as their trivial upper bound. This result generalises to puzzles of all shapes, and is applicable to both pictorial and apictorial puzzles.
متن کاملSudoku puzzles and how to solve them
A Sudoku puzzle (of ‘classical type’) consists of a 9-by-9 matrix partitioned into nine 3-by-3 submatrices (‘boxes’). Some of the entries are given, and the puzzle is to find the remaining entries, under the condition that the nine rows, the nine columns, and the nine boxes all contain a permutation of the symbols of some given alphabet of size 9, usually the digits 1-9, or the letters A-I. Som...
متن کاملSolving Jigsaw Puzzles using Paths and Cycles
There has been a growing interest in image jigsaw puzzles with square shaped pieces. A solver takes as input square shaped patches of the same size belonging to an image and attempts to reconstruct the image. The key components of a jigsaw solver are a compatibility metric and an assembly algorithm. A compatibility metric uses the color content of the image patches to identify which pairs of pi...
متن کاملShotgun Assembly of Random Jigsaw Puzzles
In a recent work, Mossel and Ross considered the shotgun assembly problem for a random jigsaw puzzle. Their model consists of a puzzle an n×n grid, where each vertex is viewed as a center of a piece. They assume that each of the four edges adjacent to a vertex, is assigned one of q colors (corresponding to ”jigs”, or cut shapes) uniformly at random. Mossel and Ross asked: how large should q = q...
