The images are synthesized with OmniPrint, no further processing was done. The OmniPrint synthesis parameters are stated as follows: font size is 192, image size is 128, the strength of random perspective transformation is 0.04, left\/right\/top\/bottom margins are all 20% of the image size, the strength of pre-rasterization elastic transformation is 0.035, random translation is activated both horizontally and vertically, image blending method is Poisson Image Editing, rotation is within -60 and 60 degrees, horizontal shear is within -0.5 and 0.5, both foreground and background are images taken from a personal mobile phone. \n\n\n\n### **Dataset Details**\n![](https:\/\/meta-album.github.io\/assets\/img\/samples\/MD_6.png)\n\n**Meta Album ID**: OCR.MD_6 \n**Meta Album URL**: [https:\/\/meta-album.github.io\/datasets\/MD_6.html](https:\/\/meta-album.github.io\/datasets\/MD_6.html) \n**Domain ID**: OCR \n**Domain Name**: Optical Character Recognition \n**Dataset ID**: MD_6 \n**Dataset Name**: OmniPrint-MD-6 \n**Short Description**: Character images with a specific set of nuisance parameters \n**\\# Classes**: 703 \n**\\# Images**: 28120 \n**Keywords**: ocr \n**Data Format**: images \n**Image size**: 128x128 \n\n**License (original data release)**: CC BY 4.0 \n**License URL(original data release)**: https:\/\/creativecommons.org\/licenses\/by\/4.0\/\n \n**License (Meta-Album data release)**: CC BY 4.0 \n**License URL (Meta-Album data release)**: [https:\/\/creativecommons.org\/licenses\/by\/4.0\/](https:\/\/creativecommons.org\/licenses\/by\/4.0\/) \n\n**Source**: OmniPrint \n**Source URL**: https:\/\/github.com\/SunHaozhe\/OmniPrint \n \n**Original Author**: Haozhe Sun \n**Original contact**: sunhaozhe275940200@gmail.com \n\n**Meta Album author**: Haozhe Sun \n**Created Date**: 25 June 2021 \n**Contact Name**: Haozhe Sun \n**Contact Email**: meta-album@chalearn.org \n**Contact URL**: [https:\/\/meta-album.github.io\/](https:\/\/meta-album.github.io\/) \n\n\n\n### **Cite this dataset**\n```\n@inproceedings{sun2021omniprint,\n title={OmniPrint: A Configurable Printed Character Synthesizer},\n author={Haozhe Sun and Wei-Wei Tu and Isabelle M Guyon},\n booktitle={Thirty-fifth Conference on Neural Information Processing Systems Datasets and Benchmarks Track (Round 1)},\n year={2021},\n url={https:\/\/openreview.net\/forum?id=R07XwJPmgpl}\n}\n```\n\n\n### **Cite Meta-Album**\n```\n@inproceedings{meta-album-2022,\n title={Meta-Album: Multi-domain Meta-Dataset for Few-Shot Image Classification},\n author={Ullah, Ihsan and Carrion, Dustin and Escalera, Sergio and Guyon, Isabelle M and Huisman, Mike and Mohr, Felix and van Rijn, Jan N and Sun, Haozhe and Vanschoren, Joaquin and Vu, Phan Anh},\n booktitle={Thirty-sixth Conference on Neural Information Processing Systems Datasets and Benchmarks Track},\n url = {https:\/\/meta-album.github.io\/},\n year = {2022}\n }\n```\n\n\n### **More**\nFor more information on the Meta-Album dataset, please see the [[NeurIPS 2022 paper]](https:\/\/meta-album.github.io\/paper\/Meta-Album.pdf) \nFor details on the dataset preprocessing, please see the [[supplementary materials]](https:\/\/openreview.net\/attachment?id=70_Wx-dON3q&name=supplementary_material) \nSupporting code can be found on our [[GitHub repo]](https:\/\/github.com\/ihsaan-ullah\/meta-album) \nMeta-Album on Papers with Code [[Meta-Album]](https:\/\/paperswithcode.com\/dataset\/meta-album) \n\n\n\n### **Other versions of this dataset**\n[[Micro]](https:\/\/www.openml.org\/d\/44280) ", "format": "arff", "uploader": "Meta Album", "uploader_id": 30980, "visibility": "public", "creator": "\"Ihsan Ullah\"", "contributor": null, "date": "2022-10-28 16:28:54", "update_comment": null, "last_update": "2022-10-28 16:28:54", "licence": "CC BY-NC 4.0", "status": "active", "error_message": null, "url": "https:\/\/api.openml.org\/data\/download\/22111010\/dataset", "kaggle_url": null, "default_target_attribute": "CATEGORY", "row_id_attribute": null, "ignore_attribute": null, "runs": 0, "suggest": { "input": [ "Meta_Album_MD_6_Mini", "## **Meta-Album OmniPrint-MD-6 Dataset (Mini)** OmniPrint-MD-6 dataset consists of 28 120 images (128x128, RGB) from 703 categories.
