Using a camera, these were taken to a 3024 by 3024 pixels frame size within RGB color space. 130 photos were taken from each person, 5 per class (minor changes on sample sizes in classes can be observed) - 26 classes containing phrases, letters, and numbers with a 27th class null category made up of 314 images for control purposes. The main motivation was contributing to technology development use cases that can reduce the communication challenges faced speech-impaired people with new data to meet the diversity and sample size necessary for intelligent computer vision studies and sign language applications.","description_withheld":null,"homepage":"https://www.kaggle.com/datasets/ardamavi/27-class-sign-language-dataset","introduced_date":"2022-03-08","introduced_date_note":null,"introduced_by":{"paper":"/paper/a-new-27-class-sign-language-dataset","title":"A New 27 Class Sign Language Dataset Collected from 173 Individuals","first_author":"Arda Mavi","url":null},"license":{"name":"Unko - Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","url":"https://creativecommons.org/licenses/by-nc-sa/4.0/"},"modalities":[],"tasks":[],"languages":[{"name":"American Sign Language","url":"/datasets/language/american-sign-language"}],"variants":["27 Class ASL Sign Language"],"data_loaders":[],"num_papers_in_archive":2,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
