Richard Hartley

Australian National University

Richard is renowned as one of the founders of the field of multi-view geometry in computer vision – his text has received over 28,000 citations.  He contributes to the Centre’s Camera Hardware and Learning for Vision projects. Richard has been at ANU since January 2001. He was also the Program Leader for the Autonomous Systems and Sensor Technology Program of NICTA.  Richard worked at the General Electric Research and Development Center from 1985 to 2001, where he became involved with Image Understanding and Scene Reconstruction working with GE’s Simulation and Control Systems Division. This division built large-scale flight-simulators. Dr. Hartley’s projects in this area were in the construction of terrain models and texture mosaics from aerial and satellite imagery. From 1995 he was GE project leader for a shared-vision project with Lockheed-Martin involving design and implementation of algorithms for an AFIS (fingerprint analysis) system being developed under a Lockheed-Martin contract with the FBI. This involved work in feature extraction, interactive fingerprint editing and fingerprint database matching. In 2000, he co-authored (with Andrew Zisserman) a book for Cambridge University Press, summarizing the previous decade’s research in this area. (Over 60,000 citations and an h-index of 78).

Dylan Campbell

Australian National University

Dylan joined the Centre as a Research Fellow at the ANU in August 2018. Previously, he was a PhD student at ANU and Data61/CSIRO, where he worked on geometric vision problems, and a research assistant in the Cyber-Physical Systems group of Data61/CSIRO, where he worked on Resource Constrained Vision.  Dylan received a BE in Mechatronic Engineering from the University of New South Wales. He has broad research interests within computer vision and robotics, including geometric vision and human-centred vision. In particular, he has investigated geometric sensor data alignment problems, such as camera localisation, simultaneous localisation and mapping, and structure from motion.

He is currently looking at the problems of recognising, modelling, and predicting human actions, poses and human-object interactions with a view to facilitate robot-human interaction as part of a Centre project.

Yizhak (Itzik) Ben-Shabat

Australian National University

Itzik joined the Centre as a Research Fellow at the ANU node in July 2019. Previously, he was a PhD student at Technion Israel Institute of Technology where he worked on “Classification, segmentation, and geometric analysis of 3D point clouds using deep learning” under the supervision of Professor Anath Fischer and Michael Lindenbaum. Itzik completed his Bsc. Cum Laude in 2008 and his Msc. Summa Cum Laude in 2015 (Mechanical Engineering, Technion). His research interests lie at the intersection of robotic perception, 3D computer vision, and geometric analysis, usually using 3D point cloud data.

During his time at the Centre, he played a key role in the IKEA assembly dataset team, joined the RVSS organizing committee and presented DeepFit, a novel surface fitting method, at ECCV 2020 as an oral presentation./  His mission is to make beautifully practical and accessible 3D data algorithms to change the world.

Project Aim

To understand human actions and intent, robots need to make inferences from visual and motion cues, just like humans do. This research project expands the capabilities of robots by building representations and models that allow a robot to understand human activity and the interaction of humans with objects in their environment. The research is important because it will ultimately enable robots to co-operate with humans to complete complex task in unstructured environments; for example, assembling a piece of furniture in the home.


Key Results

In 2020, the project team continue to make important scientific contributions to solving the problems of human activity recognition and forecasting. Two papers by Centre researchers (Fatemeh Saleh, Xin Yu and Hongdong Li) and colleagues received best paper nominations at the 2020 conference for Computer Vision and Pattern Recognition (CVPR), for work on saliency detection and sign language recognition, respectively, which also has applications in understanding human gestures for human-robot cooperation. Another paper by Centre researchers Cristian Rodriguez Opazo, Xin Yu, Hongdong Li and collaborator Dongxu Li also received an honourable mention at the 2020 Winter Conference on Applications of Computer Vision (WACV).

Project Leader, Stephen Gould, Professor Richard Hartley and Postdoctoral Fellow, Dylan Campbell presented a workshop at CVPR 2020 on Deep Declarative Networks, which received a Centre award for Best Profile Raising Event in Robotics and Computer Vision Communities. This was followed up with a tutorial on the same topic organised by Postdoctoral Fellow Itzik Ben-Shabat was held at the European Conference on Computer Vision (ECCV) and included presentations by colleagues from Stanford and Facebook.

The team also published the Ikea Assembly dataset at WACV. The dataset is a multi-modal and multi-view video collection of furniture assembly tasks to enable rich analysis and understanding of human activities. It contains 371 samples of furniture assemblies and their ground-truth annotations. Each sample includes 3 RGB views, one depth stream, atomic actions, human poses, object segments, object tracking, and extrinsic camera calibration. The videos, annotations and associated code for data processing have been publicly released to the research community and were including it in the Best of ACRV Repository that is available on the Centre’s Legacy Website.

The dataset enabled a demonstration of human-robot cooperation in assembling a small Ikea table in collaboration with the Manipulation Project. The demo led by Postdoctoral Fellow Itzik Ben-Shabat and PhD Student Zheyu Zhuang, was showcased at RoboVis 2020. Discussion with Ikea Sweden are underway on research collaborations that can further extend this work.

The end of the year saw several our research team take up new positions as the Centre comes to close. Postdoctoral Fellow Dylan Campbell has taken up a position with the Visual Geometry Group at Oxford University, Itzik Ben-Shabat has commenced a prestigious three-year Marie-Curie Fellowship, and PhD student Cristian Rodriguez successfully submitted his PhD titled “Video Analysis for Understanding Human Actions and Interactions”. Postdoctoral Fellow Fatemeh Saleh and PhD Student Sadegh Aliakbarian were also awarded a DSTG grant to research player analytics and forecasting.
