In this study, we focus on depth-based detection of standing-pigs with \u201cmoving noises\u201d, which appear every night in a commercial pig farm, but have not been reported yet. We first apply a spatiotemporal interpolation technique to remove the moving noises occurring in the depth images. Then, we detect the standing-pigs by utilizing the undefined depth values around them. Our experimental results show that this method is effective for detecting standing-pigs at night, in terms of both cost-effectiveness (using a low-cost Kinect depth sensor) and accuracy (i.e., 94.47%), even with severe moving noises occluding up to half of an input depth image. Furthermore, without any time-consuming technique, the proposed method can be executed in real-time.<\/jats:p>","DOI":"10.3390\/s17122757","type":"journal-article","created":{"date-parts":[[2017,11,30]],"date-time":"2017-11-30T03:15:15Z","timestamp":1512011715000},"page":"2757","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":61,"title":["Depth-Based Detection of Standing-Pigs in Moving Noise Environments"],"prefix":"10.3390","volume":"17","author":[{"given":"Jinseong","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong City 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeonwoo","family":"Chung","sequence":"additional","affiliation":[{"name":"Department of Applied Statistics, Korea University, Sejong City 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Younchang","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong City 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6470-3341","authenticated-orcid":false,"given":"Jaewon","family":"Sa","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong City 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heegon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong City 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongwha","family":"Chung","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong City 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daihee","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Science, Korea University, Sejong City 30019, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hakjae","family":"Kim","sequence":"additional","affiliation":[{"name":"Class Act Co., Ltd., Digital-ro, Geumcheon-gu, Seoul 08589, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,11,29]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Precision Livestock Farming: An International Review of Scientific and Commercial Aspects","volume":"5","author":"Banhazi","year":"2012","journal-title":"Int.
