![]() Regardless, you will have time to connect with loved ones over a shared activity that invites cooperative behavior. When you start 500-piece jigsaw puzzles of a Pokémon scene or an old-timey post office with a group, you know you can probably complete them in just a few hours, depending on the relative difficulty of the image and the skill and commitment of those involved. While some enjoy solo puzzling, others like to socialize by building puzzles with family or friends. When you turn to a machine to do the hard work for you, the activity won’t engender the same feelings of relaxation and satisfaction that draw you to puzzling in the first place. Many people use this activity to escape from the stresses of daily life, let their problems slip away for a while, and focus on something that engages them completely. Those who attempt complex jigsaw puzzles for adults, like a daunting, 2000-piece Star Wars puzzle, are often attracted to the process. There simply isn’t much call for apps to solve jigsaw puzzles, likely because most people aren’t keen to “cheat,” so to speak. While the potential of this workshop project is certainly exciting, the sample puzzle used only contains 54 pieces, not the 500-piece puzzles (or more) you’re probably used to. Complex algorithms accomplish the many steps of this process nearly automatically, and the final step is to create a visual rendering of the pieces coming together to form the final image. The program also uses colors to match up pieces, some of which may have extremely similar contours. Finally, elimination occurs as the pieces are joined, and versions of alignment that are no longer needed are discarded. Next, the program determines the orientation of pieces within the puzzle, creating several versions that accommodate different rotations. The program notes multiple points of convexity so it can align the pieces in an “upright” position. Next, the program identifies the inner and outer locks on the pieces (also commonly referred to as “tabs” or protrusions and “blanks” or cut-ins). The process begins with cropping or separating the puzzle pieces from the background color to create unique contours for the pieces. It just does it a lot faster and without the aid of the original image to work from. How does it work? It uses pattern recognition, which is surprisingly similar to the human brain's ability to solve puzzles. This is the basic approach behind the Automatic Jigsaw Puzzle Solver from Abto Software. It makes sense that the same type of software might be used to piece a puzzle together. ![]() You may have heard of computer programs that can take scanned information, such as pieces of shredded documents, and reassemble the source material to reconstruct the original image. Additionally, it can only solve puzzles up to 50 pieces, so even with 100 or 300-piece puzzles, you’re out of luck. For one thing, most people don’t use Linux, and it may not be compatible with Windows, not to mention mobile applications. There are two potential downsides to this program, though. It does so using a binary process of comparing the original image and the pieces, cataloging the perimeter of pieces, separating pieces into categories, and then matching them up. The Zolver program, created by students in Python for Linux, is designed to solve real-world and virtual puzzles. What are these apps? How do they work, and can they help you complete 1000-piece jigsaw puzzles that have you stumped? Zolver ![]() If you’re not making much headway and days are turning into weeks with a puzzle left partially finished on a table that you need for other purposes, you might start looking for a bit of help.Īre there apps that can assist you in unpuzzling the pieces you have left on your colorful Aimee Stewart puzzle, or at least give you a leg up to get past a block and proceed?Īs it turns out, there are a few apps designed for this purpose, but neither may be terribly useful to the average puzzle aficionado. Getting stuck on a complex, 2000-piece puzzle - particularly one you started with others but were left to finish alone - can be frustrating. Maybe you just want a fun way to spend an afternoon with family or friends. Sometimes, you want to work on a puzzle to relax, refresh, and refocus your mind. Indeed, the challenge makes completing a particularly difficult puzzle feel like a hard-won victory. Like any kind of puzzle, jigsaw puzzles can be both exciting and challenging.
