BOORU CHARS OPEN DATASET is an attempt to consolidate and arrange available character-centric almost-SFW anime/CG/game art in localized form suited both for batch processing and visual estimation **This release of BOORU CHARS consist of :** - **1.593.429 sample images**, mogrified to 1280px (1024px for 1х1) * grouped into 18 volumes (directories) by aspect ratio and year * zipped by 1000 images according to statistics similarity * with verbose file naming **%website% - %id% - %copyright% ~ %characters% (%artist%)** * with some tags placed into EXIF - several tab-separated texts with metadata * post/image info (for samples, originals and from imageboard) 1.593.429 rows * collected tag info with some addons - 35.222.997 rows * listing for 32 torrents total with 3.839.005 pictures (almost 5 ТБ - the basis of dataset) - an example of dataset usage for body objects detection and character "assembling" * detector [notAI-tech NudeNet](https://github.com/notAI-tech/NudeNet) results for 2 volumes and composed output listings * ~4000 most interesting visualisations (samples with detections drawn) - some verbose descriptions * **readme_RU/EN** with code examples and a lot of references * several zipped Excels with analytic results and SQL-s * some illustrative screenshots **The main features of dataset are:** - several sources but unique image identification **%website% + %id%** * original images can be found in torrents (nyaa, rutracker) * selective regrab of originals possible if source website available - careful deduplication with relative website priorities, high to low (mostly) * safebooru.org * yande.re * gelbooru.com * anime-pictures.net * konachan.com * zerochan.net * chan.sankakucomplex.com * danbooru.donmai.us * e-shuushuu.net * tbib.org - segmentation by chronology (estimated year of release) and by aspect ratio * "artbook pages" **7x10 (+/- 4%)** * “wide pages” **3x4 (+/- 10%)** * “squares” **1x1 (+/- 20%)** * “wallpapers and computer screens” **3x2 (+/- 40%)** * "tall pages" **2x3 (+/- 40%)** folder name contains 1x2 - rather high original images technical and visual quality * width>=900 height>=900 MPixels>=1.2 * most of comixes, lineart, overtexted images excluded, no photo, almost no characterless scenes - not completely SFW (a little bit sotfcore ecchi here and there) Earlier version of this dataset [(2019, 512px)](https://nyaa.iss.one/view/1206322) has to be treated as obsolete. I hope that this half-terabyte of data worth more than the same size chia coin mining pool. NOTE-1 several standalone [not SFW datasets at Sukebei](https://fap.iss.one/user/AlexPUA) also with sample images, metadata and some analysis done. NOTE-2 neural network architecture [YOLO](https://github.com/ultralytics/ultralytics) seems to be very good for art. I already have [promising results](https://github.com/aperveyev/booru_yolo), stay tuned. NOTE-3 there is similar [BOORU CHARS 2015 dataset](https://nyaa.iss.one/view/1468367) for "early art" NOTE-4 next [BOORU CHARS 2022](https://nyaa.iss.one/view/1547662) release over volumes: [2021 b-c-d](https://nyaa.iss.one/view/1462329) and [2022 a-b](https://nyaa.iss.one/view/1539363)
