At some point, all of us enjoyed and solved puzzles. The panic of a missing piece and the joy of completing puzzles was exciting! This challenge will try to recreate the retro-puzzle solving with an AI twist! Given a set of jumbled images, can you sort them in the correct order to solve the puzzle and form the complete picture? The mission, if you choose to accept, is to classify and sort the many jumbled images in the correct order and submit a final solution with the correct order number. `````` ashivani committed Oct 06, 2020 16 ``````

The height and widhth of original image can be found in the `metadata.csv` . There are total `2500` such folders, with puzzle pieces of the respective image ids. # 📁 Files Following files are available in the `resources` section: * `puzzles.tar.gz`: A tar.gz file which when extracted, has 2500 folders (where folder names are the puzzle-id), and each of the folders contain the individual puzzle pieces comprising this puzzle as PNG files. * `sample_submission.tar.gz`: A tar.gz file with 2500 randomly reconstructed images of each of the puzzles in the test set. The naming convention for each of the files inside this tar is `.jpg`. * `metadata.csv` : A file containing the width and height of each of the puzzles in the test set. # 🚀 Submission - Recreate the original images with the puzzle pieces given in each folder for an image. - Name the image as `{image_id}.jpg` - Create a `tar.gz` file containing all the recreated images. - For eg ``` submission.tar.gz ├── 0.jpg |── 1.jpg └── .... ``` - `Sample_submission.tar.gz` can be found in resources section. `````` ashivani committed Oct 06, 2020 45 ``````**Make your first submission [here](https://www.aicrowd.com/challenges/jigsaw/submissions/new) 🚀 !!** `````` ashivani committed Oct 06, 2020 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 `````` # 🖊 Evaluation Criteria This challenge uses the [SSIM score](https://en.wikipedia.org/wiki/Structural_similarity) as the primary evaluation metric and the [Mean Squared Error](https://en.wikipedia.org/wiki/Mean_squared_error). For all the puzzles in the dataset, the individual scores are computed by comparing the submitted reconstructed image in reference to the original image. The overall submission score is the mean SSIM and MSE scores across the whole data **The score of only 60% of the test data will be revealed during the competition.** # 🔗 Links * 💪 Challenge Page: [https://www.aicrowd.com/challenges/jigsaw](https://www.aicrowd.com/challenges/jigsaw) * 🗣️ Discussion Forum: [https://www.aicrowd.com/challenges/jigsaw/discussion](https://www.aicrowd.com/challenges/jigsaw/discussion) * 🏆 Leaderboard: [https://www.aicrowd.com/challenges/jigsaw/leaderboards](https://www.aicrowd.com/challenges/jigsaw/leaderboards) # 📱 Contact - [Sharada Mohanty](mailto:mohanty@aicrowd.com)``````
