The effectiveness of FER systems mainly depends on the extracted features. For extracting distinctive features with low dimensions, a new local texture-based image descriptor named Dimensionality Reduced Chess Pattern (DRCP) is proposed for recognizing facial expressions in a person independent scenario. DRCP, an improvement over Chess Pattern (CP), is mainly proposed for effectively reducing the feature vector length of CP.\u00a0For feature extraction, DRCP also considers the movements of chessmen in a [Formula: see text] neighborhood, as like CP. As a part of feature extraction through DRCP, apart from the center pixel, the remaining 24 pixels are arranged into four groups in such a manner that each group contains the pixels corresponding to three chessmen. From each group, one feature is extracted and thus corresponding to four groups, four features are extracted in a [Formula: see text] neighborhood. The extracted features are fed into multi-class Support Vector Machine (SVM) for expression recognition. The experiments are performed on five \u201cin the lab\u201d datasets (MUG, TFEID, JAFFE, CK[Formula: see text] and KDEF) and on two \u201cin the wild\u201d datasets (RAF and SFEW) in person independent setup to simulate a real world scenario. <\/jats:p>","DOI":"10.1142\/s021800142256016x","type":"journal-article","created":{"date-parts":[[2022,6,4]],"date-time":"2022-06-04T15:48:34Z","timestamp":1654357714000},"source":"Crossref","is-referenced-by-count":5,"title":["DRCP: Dimensionality Reduced Chess Pattern for Person Independent Facial Expression Recognition"],"prefix":"10.1142","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5502-4884","authenticated-orcid":false,"given":"Mukku Nisanth","family":"Kartheek","sequence":"first","affiliation":[{"name":"Institute for Development and Research in Banking Technology, Masab Tank, Hyderabad, Telangana, India"},{"name":"Department of Computer Science and Engineering, National Institute of Technology, Warangal, Telangana, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Munaga V.\u00a0N.\u00a0K.","family":"Prasad","sequence":"additional","affiliation":[{"name":"Institute for Development and Research in Banking Technology, Masab Tank, Hyderabad, Telangana, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raju","family":"Bhukya","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, National Institute of Technology, Warangal, Telangana, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,8,5]]},"reference":[{"key":"S021800142256016XBIB001","doi-asserted-by":"publisher","DOI":"10.1007\/s00371-016-1323-z"},{"key":"S021800142256016XBIB002","first-page":"1","volume-title":"11th Int.
