“…This problem was solved by using the power of transfer learning with a pre-trained model using the TF Object Detection API (Adrian Rosebrock, 2017). Doors' detection using DL has already been addressed for indoor robot navigation with social, assistance or domestic applications, as more detailed in section 2 (Banerjee, Long, Du, Polido, Feng, Atkeson, Gennert, & Padir, 2015;Borgsen, Schöpfer, Ziegler, & Wachsmuth, 2014;Chen, Qu, Zhou, Weng, Wang, & Fu, 2014;Dai et al, 2013;Derry & Argall, 2013;Fernández-Caramés, Moreno, Curto, Rodríguez-Aragón, & Serrano, 2014;He & Zhu, 2017;Kakillioglu, Ozcan, & Velipasalar, 2016;Lecrosnier et al, 2021;Llopart, Ravn, & Andersen, 2017;Othman & Rad, 2020;Quintana, Prieto, Adán, & Bosché, 2018;Ramoa, Alexandre, & Mogo, 2020;Sekkal, Pasteau, Babel, Brun, & Leplumey, 2013;Shalaby, Salem, Khamis, & Melgani, 2014;Spournias, Antonopoulos, Keramidas, Voros, & Stojanovic, 2020;Tian, Yang, Yi, & Arditi, 2013;Yuan, Hashim, Zaki, & Huddin, 2016). However, these studies did not address PD problem, a contribution introduced by this work.…”
