Despite recent progress in crafting deep learning-centric IPPG methodologies, which predominantly forge a correlation between spatiotemporal heart rate (HR) feature imagery and corresponding HR readings, these techniques encounter constraints in extended spatiotemporal comprehension and engagement. In this manuscript, we introduce the BiFormer architecture, an end-to-end solution integrating temporal difference convolution, multi-head self-attention transformer modules, and bidirectional long short-term memory networks to refine signal estimations and bolster the model\u2019s discernment prowess. Our framework was appraised through intra-database and inter-database evaluations on three accessible datasets, evidencing superiority over conventional IPPG strategies in HR accuracy metrics. Notably, assessments on the VIPL-HR dataset indicated a reduction in the average root mean square error to 7.24 beats per minute.<\/jats:p>","DOI":"10.3233\/faia231195","type":"book-chapter","created":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T12:55:47Z","timestamp":1705064147000},"source":"Crossref","is-referenced-by-count":2,"title":["BiFormer: An End-to-End Deep Learning Approach for Enhanced Image-Based Photoplethysmography and Heart Rate Accuracy"],"prefix":"10.3233","author":[{"given":"Shaohua","family":"Liu","sequence":"first","affiliation":[{"name":"School of Electronic Engineering, Beijing University of Posts and Telecommunications, China"}]},{"given":"Yuchong","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Beijing University of Posts and Telecommunications, China"}]},{"given":"XingJian","family":"Jing","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, City University of Hong Kong, China"}]},{"given":"Bin","family":"Li","sequence":"additional","affiliation":[{"name":"First Clinical Medical College, Guangzhou University of Chinese Medicine, China"}]},{"given":"Hao","family":"Liu","sequence":"additional","affiliation":[{"name":"Peking University Shougang Hospital, China"}]},{"given":"Shangwei","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Beijing University of Posts and Telecommunications, China"}]},{"given":"Chundong","family":"She","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Beijing University of Posts and Telecommunications, China"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Electronics, Communications and Networks"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA231195","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T12:55:49Z","timestamp":1705064149000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA231195"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1,12]]},"ISBN":["9781643684802","9781643684819"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia231195","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,1,12]]}}}
