Recent developments in low-cost infrared (IR) sensors, compatible with smartphones, provide competitive advantages for home-monitoring applications. However, these sensors present reduced capabilities compared to more expensive high-end devices. In this work, the characterization of thermal cameras is described and carried out. This characterization includes non-uniformity (NU) effects and correction as well as the thermal cameras\u2019 dependence on room temperature, noise-equivalent temperature difference (NETD), and response curve stability with temperature. Results show that low-cost thermal cameras offer good performance, especially when used in temperature-controlled environments, providing evidence of the suitability of such sensors for medical applications, particularly in the assessment of diabetic foot ulcers on which we focused this study.<\/jats:p>","DOI":"10.3390\/s20051321","type":"journal-article","created":{"date-parts":[[2020,3,3]],"date-time":"2020-03-03T03:13:28Z","timestamp":1583205208000},"page":"1321","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["Performance Assessment of Low-Cost Thermal Cameras for Medical Applications"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1028-6957","authenticated-orcid":false,"given":"Enrique","family":"Villa","sequence":"first","affiliation":[{"name":"IACTEC Medical Technology Group, Instituto de Astrof\u00edsica de Canarias (IAC), c\\\u00c1lvaro Mart\u00edn D\u00edaz 2, 38320 La Laguna, Tenerife, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1645-0810","authenticated-orcid":false,"given":"Natalia","family":"Arteaga-Marrero","sequence":"additional","affiliation":[{"name":"IACTEC Medical Technology Group, Instituto de Astrof\u00edsica de Canarias (IAC), c\\\u00c1lvaro Mart\u00edn D\u00edaz 2, 38320 La Laguna, Tenerife, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3545-2328","authenticated-orcid":false,"given":"Juan","family":"Ruiz-Alzola","sequence":"additional","affiliation":[{"name":"IACTEC Medical Technology Group, Instituto de Astrof\u00edsica de Canarias (IAC), c\\\u00c1lvaro Mart\u00edn D\u00edaz 2, 38320 La Laguna, Tenerife, Spain"},{"name":"Departamento de Se\u00f1ales y Comunicaciones, Instituto Universitario de Investigaci\u00f3n Biom\u00e9dica y Sanitaria (IUIBS), Universidad de Las Palmas de Gran Canaria, c\\Paseo Blas Cabrera Felipe \u201cF\u00edsico\u201d s\/n, 35016 Las Palmas de Gran Canaria, Las Palmas, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"279","DOI":"10.2478\/s11772-012-0037-7","article-title":"History of Infrared Detectors","volume":"20","author":"Rogalski","year":"2012","journal-title":"Opto-Electron.
