Bridging the Gap Between Computational Photography and Visual Recognition:
UG2+ Prize Challenge
CVPR 2020
$6K in prizes

The rapid development of computer vision algorithms increasingly allows automatic visual recognition to be incorporated into a suite of emerging applications. Some of these applications have less-than-ideal circumstances such as low-visibility environments, causing image captures to have degradations. In other more extreme applications, such as imagers for flexible wearables, smart clothing sensors, ultra-thin headset cameras, implantable in vivo imaging, and others, standard camera systems cannot even be deployed, requiring new types of imaging devices. Computational photography addresses the concerns above by designing new computational techniques and incorporating them into the image capture and formation pipeline. This raises a set of new questions. For example, what is the current state-of-the-art for image restoration for images captured in non-ideal circumstances? How can inference be performed on novel kinds of computational photography devices?

Continuing the success of the 1st (CVPR'18) and 2nd (CVPR'19) UG2 Prize Challenge workshops, we provide its 3rd version for CVPR 2020. It will inherit the successful benchmark dataset, platform and evaluation tools used by the first two UG2 workshops, but will also look at brand new aspects of the overall problem, significantly augmenting its existing scope.

Original high-quality contributions are solicited on the following topics:
  • Novel algorithms for robust object detection, segmentation or recognition on outdoor mobility platforms (UAVs, gliders, autonomous cars, outdoor robots etc.), under real-world adverse conditions and image degradations (haze, rain, snow, hail, dust, underwater, low-illumination, low resolution, etc.)
  • Novel models and theories for explaining, quantifying, and optimizing the mutual influence between the low-level computational photography tasks and various high-level computer vision tasks, and for the underlying degradation and recovery processes, of real-world images going through complicated adverse visual conditions.
  • Novel evaluation methods and metrics for image restoration and enhancement algorithms, with a particular emphasis on no-reference metrics, since for most real outdoor images with adverse visual conditions it is hard to obtain any clean “ground truth” to compare with.

What is the current state-of-the-art for image restoration for images captured in non-ideal circumstances? How can inference be performed on novel kinds of computational photography devices?

The UG2+ Challenge seeks to advance the analysis of "difficult" imagery by applying image restoration and enhancement algorithms to improve analysis performance. Participants are tasked with developing novel algorithms to improve the analysis of imagery captured under problematic conditions.

Object Detection in Poor Visibility Environments

While most current vision systems are designed to perform in environments where the subjects are well observable without (significant) attenuation or alteration, a dependable vision system must reckon with the entire spectrum of complex unconstrained and dynamic degraded outdoor environments. It is highly desirable to study to what extent, and in what sense, such challenging visual conditions can be coped with, for the goal of achieving robust visual sensing

Sub-Challenges

  1. Object Detection in the Hazy & Rainy Condition
  2. Face Detection in the Low-Light Condition
  3. Sea Life Detection in the Underwater Condition

Face Verification on FlatCam Images

The FlatCam is a lensless camera whose thin and inexpensive design allows its easy integration into numerous applications for various computer vision tasks. However, FlatCam images contain noise and artifacts unseen in standard lens-based cameras, an issue that degrades its performance in such tasks. This challenge explores new algorithms to better integrate lensless cameras into computer vision applications by using face verification as a working example.

Sub-Challenges

  1. Image Enhancement for FlatCam Face Verification
  2. Image Reconstruction for FlatCam Face Verification
  3. End-to-End Face Verification on FlatCam Measurements
