In this work, we focus on a set of the population which is probably the most vulnerable: children. Specifically, we present\n            <jats:italic>ChildSafe<\/jats:italic>\n            , a classification system that exploits ratios of skeletal features extracted from children and adults using a 3D depth camera to classify visual characteristics between the two age groups. Specifically, we combine the ratio information into one bag-of-words feature for each sample, where each word is a histogram of the ratios. ChildSafe analyzes the words that are normalized within and between the two age groups and implements a fuzzy bin-based classification method that represents bin-boundaries using fuzzy sets. We train and evaluate ChildSafe using a large dataset of visual samples collected from 150 elementary school children and 150 adults, ranging in age from 7 to 50. Our results suggest that ChildSafe successfully detects children with a proper classification rate of up to 94%, a false-negative rate as low as 1.82%, and a low false-positive rate of 5.14%. We envision this work as a first step, an effective subsystem for designing child safety applications.\n          <\/jats:p>","DOI":"10.1145\/3079764","type":"journal-article","created":{"date-parts":[[2017,8,24]],"date-time":"2017-08-24T11:49:04Z","timestamp":1503575344000},"page":"1-28","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Fuzzy Bin-Based Classification for Detecting Children\u2019s Presence with 3D Depth Cameras"],"prefix":"10.1145","volume":"13","author":[{"given":"Hee Jung","family":"Yoon","sequence":"first","affiliation":[{"name":"DGIST, Daegu, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ho-Kyeong","family":"RA","sequence":"additional","affiliation":[{"name":"DGIST, Daegu, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Can","family":"Basaran","sequence":"additional","affiliation":[{"name":"HERE, Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang Hyuk","family":"Son","sequence":"additional","affiliation":[{"name":"DGIST, Daegu, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taejoon","family":"Park","sequence":"additional","affiliation":[{"name":"Hanyang University, Gyeonggi-do, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeonggil","family":"Ko","sequence":"additional","affiliation":[{"name":"Ajou University, Gyunggi-Do, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2017,8,16]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"ISO specification for car child seat detection system will help reduce risk of injury from airbags.
