Transparent & Reflective objects In the wild Challenges

October 3rd, morning session

From industry to the home, vision systems are expected to provide relevant information for every object they may encounter in their environment. Vision-based object understanding in particular has seen significant progress toward this goal as demonstrated, for example, by recent results in challenges such as the COCO, and its follow-up LVIS challenge, or the Benchmark for 6D Object Pose Estimation.

Transparent, reflective and, generally speaking, non-lambertian objects still present major challenges for methods as well as RGB and depth sensors. Color images become dependent on the viewpoint and background. Similarly, readings from depth cameras are unreliable whether they are based on stereo matching, time-of-flight or structured light. The unpredictable and unreliable data is problematic at two different levels. On one hand, such objects will not reliably be understood but their presence in the scene degrades the understanding of other objects in the scene through reflections and light path deformation.

The workshop on Transparent & Reflective objects In the wild Challenges (TRICKY) will discuss object classification, detection, tracking, reconstruction, depth and pose estimation from imaging data for such tricky objects with the aim of advancing the state-of-the-art and fostering novel research directions. A major focus will be put on the applicability of methods in unconstrained scenarios. Check the program for more details.

We invite submission of 4 page (excluding references) extended abstracts (following the ICCV 2023 template) on topics related to transparent and reflective object understanding. Reviewing of abstract submissions will be double-blind. The purpose of this workshop is not to be a venue for publication but rather a place to discuss and open new directions of research for transparent and reflective objects understanding, as well as gather a community of people interested in the field. The workshop proceedings will not appear in the official ICCV 2023 workshop proceedings. Submissions of work which has been previously published, including papers accepted to the main ICCV 2023 conference are allowed.

As part of the workshop schedule, 6 submitted papers will be selected for a spotlight presentation as contributed talks, and all accepted abstracts will be presented during the poster session. 


Relevant topics for this workshop include transparent and or reflective objects:


We are happy to announce that the following papers will be presented during the spotlight session of the workshop:
