This workshop aims to bring together researchers working on 3D computer vision and graphics for eCommerce, with a focus on the three topics: (1) 3D object/scene modeling and understanding in 3D eCommerce such as semantic segmentation, affordance and motion, multi-view reconstruction; (2) human modeling and fashion in 3D eCommerce such as virtual try-ons and personalized fashion recommendation, and (3) language-assisted reasoning such as shape/scene synthesis from texts and language grounding in 3D models. We invited 6 keynote speakers from academia and 3 talks from industry experts. We will also host a challenge on 3D part labeling for 3D models from real products sold online.

She has (co-)authored more than 300 refereed publications in these areas and co-edited/authored four books. Many of Lin’s research findings have been patented and licensed by more than 50 companies world wide. Lin is an Amazon Scholar with Amazon Fashion.

Roozbeh Mottaghi Research Scientist Manager at Meta and Affiliate Associate Prof. at the University of Washington working on Vision-and-Language and Embodied AI. Prior to joining FAIR, he was the Research Manager of the PRIOR team at the Allen Institute for AI. Before that, I was a Postdoctoral Researcher in the Computer Science Department at Stanford University. He was a post-doctoral researcher at the Computer Science Department at Stanford University. He obtained his PhD in Computer Science from University of California, Los Angeles.

Katerina Fragkiadaki Assistant Professor in the Machine Learning Department at Carnegie Mellon University. She received her Ph.D. from the University of Pennsylvania and was a postdoctoral fellow at UC Berkeley and Google research after that. Her work is on learning visual representations with little supervision and combining spatial reasoning in deep visual learning. Her group develops algorithms for mobile computer vision, learning of physics, and common sense for agents that move around and interact with the world.

Eric Bennett Director of Science at Amazon Imaging. Bennett leads the research and development of cutting-edge solutions for the creation of 3D models using ML, CV, photogrammetry, and more to bring new immersive experiences to Amazon's customers. He obtained his Ph.D. in Computer Science from University of North Carolina at Chapel Hill.

Chengfei Lv Head of Alibaba's 3D/XR Technology Department. His team works on 3D/XR technologies specific to eCommerce, such as 3D reconstruction of commodities, high-performing volumetric video for MR, and 3D modeling and rendering engines, responsible for exploring innovative consumer applications for immersive experiences.


Call for particpations: The workshop will host a competition focused on fine-grained semantic segmentation of 3D shapes. The competition will use 3D models from five categories (chair, table, cabinet, lamp, and bed) from the Amazon-Berkeley-Object (ABO) dataset, which has a total of 3400 models. The ABO dataset, recently published, features high quality, uniformly standard 3D models of real products sold online, created by artists. The models are made up of build-aware connected components, which form the basis of various shape properties such as texture, motion, function, interaction, and construction. The workshop challenge focuses on assigning fine-grained semantic labels (e.g., leg and arm, defined based on PartNet) to these connected components in the ABO dataset.
