Challenge

Competition tracks

We are hosting two separate competition tracks: The SkelNetOn Challenge and The ABC Challenge, implemented in indepentent contests available at Codalab.

SkelNetOn Challenge

The SkelNetOn Challenge is structured around shape understanding in three domains. We provide shape datasets and some complementary resources (e.g, pre/post-processing, sampling, and data augmentation scripts) and the testing platform. Submissions to the challenge will perform one of the following tasks:

  • Shape pixels to skeleton pixels: Extract skeleton pixels from a binary shape image. This is a binary classification problem where image pixels are labeled as on or off the skeleton. Now online: click here for CodaLab competition.
  • Shape points to skeleton points: Extract skeleton points from a shape point cloud. This may be treated as a binary classification problem where points are labeled as on or off the skeleton, though other formulations (e.g., transformer networks, generative models) are also acceptable.

  • Shape pixels to parametric curves: Extract a parametric representation of a network of curves of the skeleton and their radii, modeled as a degree-5 BĂ©zier curve in three dimensions (two spatial coordinates and the radius). This may be thought of as a regression problem. Now online: click here for CodaLab competition.
  • Natural images to skeleton pixels: Extract a skeleton pixels from RGB images. This may be thought of as a superset of the first track, or as a recognition problem. Now online: click here for CodaLab competition.

ABC Geometry Reconstruction Challenge

The ABC Challenge serves as a testbed for common shape analysis and geometry processing tasks. We supplement the challenge with additional software libraries, sets of large-scale standardized benchmarks (data splits, resolutions, and targets), and implementations of evaluation metrics. The first ABC challenge will be hosting a three-track contest on geometry processing, including:
