However, most of the existing works focus mainly on analyzing an adult\u2019s face and ignore the important problems: how can we recognize facial expression from a baby\u2019s face image and how difficult is it? In this paper, we first introduce a new face image database, named BabyExp, which contains 12,000 images from babies younger than two years old, and each image is with one of three facial expressions (i.e., happy, sad, and normal). To the best of our knowledge, the proposed dataset is the first baby face dataset for analyzing a baby\u2019s face image, which is complementary to the existing adult face datasets and can shed some light on exploring baby face analysis. We also propose a feature guided CNN method with a new loss function, called distance loss, to optimize interclass distance. In order to facilitate further research, we provide the benchmark of expression recognition on the BabyExp dataset. Experimental results show that the proposed network achieves the recognition accuracy of 87.90% on BabyExp.<\/jats:p>","DOI":"10.1155\/2020\/8855885","type":"journal-article","created":{"date-parts":[[2020,11,23]],"date-time":"2020-11-23T18:36:03Z","timestamp":1606156563000},"page":"1-10","source":"Crossref","is-referenced-by-count":13,"title":["Feature Guided CNN for Baby\u2019s Facial Expression Recognition"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5584-9285","authenticated-orcid":true,"given":"Qing","family":"Lin","sequence":"first","affiliation":[{"name":"Integrated Information Center of Yantai, Yantai 264003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2362-7861","authenticated-orcid":true,"given":"Ruili","family":"He","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Harbin Institute of Technology, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0971-7561","authenticated-orcid":true,"given":"Peihe","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Opto-Electronic Information Science and Technology, Yantai University, Yantai 264005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/34.895976"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2015.01130"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1097\/nmd.0000000000000453"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2017.01704"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/FG.2017.23"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-01418-6_9"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/ICCVW.2011.6130508"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/CVPRW.2010.5543262"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/FG.2018.00050"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/CVPRW.2018.00286"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/CVPRW.2019.00112"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1002\/mpr.343"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1080\/02699930903485076"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2014.01532"},{"issue":"60","key":"15","first-page":"1755","article-title":"A machine learning toolkit","volume":"10","author":"D.
