6 March 2020: The LIM Steering Committee has decided to postpone this meeting due to the increase in travel restrictions and self-quarantine requirements being issued by governments, companies, and institutions. We will post additional details related to this decision, including the new conference dates, as they become available. The LIM Steering Committee will issue more information by 13 March 2020. Please send any concerns or comments to

8:30-11:00 Registration Desk Open

9:00-10:30 Pre-conference Workshop: Understanding Color for the In-Camera Processing Pipeline
Instructor: Michael Brown, professor, York University, Toronto, Canada
This workshop provides a background on color theory and its relationship to the in-camera processing pipeline and imaging applications. The workshop, organized into two parts, starts with background on color theory and color representations, namely the CIE 1931 XYZ color space and other common color spaces such as sRGB, L*ab, and Yuv, then discusses routines applied on board cameras to convert the low-level sensor raw-RGB responses to their final standard RGB (sRGB) colors. These routines include computational color constancy (auto white balance), colorimetric conversion, image demosaicing, image denoising, tone-mapping, and general color manipulation. The workshop concludes with a discussion on various misconceptions about color and camera images made in many areas of image processing and computational computer vision. The workshop is included in the registration fee.

Interactive Posters Session + Complementary Drinks

17:30-18:30   Monday Evening Keynote
Surface Color Perception in Realistic Scenes: Previews of a Future Color Science
, Laurence Maloney, New York University (US)
Research in the past two decades has shown that surface color perception in natural scenes is profoundly connected with perception of the spatial layout of the scene. This talk describes the spatial information human observers get from scenes that affects their perception of surface color and material and what it would mean to match human performance.

  Tuesday Morning Keynote
Designing Cameras to Detect the “Invisible”: Towards Domain-Specific Computational Imaging,
Felix Heide, Princeton University (US)
Imaging has become an essential part of how we communicate with each other, how autonomous agents sense the world and act independently, and how we research chemical reactions and biological processes. Today's imaging and computer vision systems, however, often fail in the “edge cases'', for example in low light, fog, snow, or highly dynamic scenes. These edge cases are a result of ambiguity present in the scene or signal itself, and ambiguity introduced by imperfect capture systems. This talk presents several examples of computational imaging methods that resolve this ambiguity by jointly designing sensing and computation for domain-specific applications. Instead of relying on intermediate image representations, which are often optimized for human viewing, these cameras are designed end-to-end for a domain-specific task. In particular, the talk shows how to co-design automotive HDR ISPs, detection, and tracking (beating Tesla's latest OTA Model S Autopilot); how to optimize thin freeform lenses for wide field of view applications; and how to extract accurate dense depth from three gated images (beating scanning lidar, such as Velodyne's HDL64). It ends by presenting computational imaging systems that extract domain-specific information from faint measurement noise using domain-specific priors, allowing us to use conventional intensity cameras or conventional Doppler radar to image "hidden'' objects outside the direct line of sight at long ranges.
