**About the Special Issue Editors**

**Ester Martinez-Martin** is Assistant Professor at University of Alicante and Subdirector at the University Institute of Computer Research. She has been a Computer Science Engineer since 2014, and she received her Ph.D. title in 2011. Her research activity has resulted in 52 publications, including a full book in Springer and 12 articles in JCR-ranked journals (6 Q1, 3 Q2, 1 Q3, 2 Q4). She has participated in 15 international and national research projects. She has also been the editor of two books in international publishing editorials and a Special Issue of a JCR Q2 journal. She has given four tutorials at international conferences (HRI, ICINCO, IAS13, IEEE RO-MAN), one gues<sup>t</sup> lecture at IEEE SWYP19, and two gues<sup>t</sup> lectures at prestigious centers (German Aerospace Centre (DLR) and Universidade do Minho). She has done four research stays in prestigious international centers over 18 months, financed by competitive public funds. She has participated as a member of the scientific committee for several international and national conferences, and as a member of the organizing committee seven times, three of them as "organization chair". She has also been awarded five times (MUY Young Scientist Award 2019, Award of Scientific Excellence 2013, Award of Scientific Excellence 2012, Young Researcher Award in the field of engineering and architecture 2015, Google EMEA Conference & Travel Grant 2012). She is a reviewer of scientific articles, a senior member of the IEEE, and a member of AERFAI. She has participated in various scientific dissemination activities, as well as in the promotion of STEM vocations among pre-university students, especially women. In addition, she has an extensive and successful teaching career, where she disseminates her research knowledge to the new generations.

**Miguel Cazorla** is a Computer Engineer from the University of Alicante (1995) and a Ph.D. in Computer Engineering from the same University (2000). In 1995, he joined the University of Alicante as a Researcher. Since 2017, he has been Full Professor. He is an IEEE Senior Member. He has completed several stays at foreign institutions (Carnegie Mellon University, University of Sydney, and University of Edinburgh). He has published more than 50 articles indexed in JCR (with more than 20 in JCR Q1) and more than 100 publications in national and international conferences. He has directed 14 Ph.D. theses and is a principal investigator in several national projects (CICYT, Challenges). He is a member of different program committees of national and international conferences. His line of research has always been centered on computational vision. From the beginning, he applied these skills to try to solve robotic tasks. Almost since its inception in research, he has worked in the processing of 3D data. In recent years, he has diversified his lines to apply deep learning techniques to different areas (medical images, object recognition, depth estimation, identification of traffic objects, etc.). All his research in recent years has been focused on social robotics and the application of all these techniques to help dependents.

**Sergio Orts-Escolano** received his B.Sc., M.Sc., and Ph.D. in Computer Science from the University of Alicante (Spain) in 2008, 2010, and 2014, respectively. He is currently a Research Scientist at Google. Previously, he was a Professor in the Department of Computer Science and Artificial Intelligence at the University of Alicante. Before joining academia, he worked at Microsoft Research, where he was one of the leading members of the Holoportation project (virtual 3D teleportation in real-time). He has collaborated and done multiple research/teaching stays at various top universities, including University of Edinburgh, University of Westminster, and University of Ljubljana. His research interests include computer vision, 3D sensing, robotics, real-time computing, GPU computing, VR/AR, and deep learning. He has authored 80+ publications, including 40+ in top JCR journals such as *CVIU*, *PRL*, *Neurocomputing*, and *TOG*. His work has been presented at top conferences such as CVPR, SIGGRAPH, 3DV, IROS, and BMVC. He is also a member of European networks like HiPEAC and Eucog.
