Competition

VIPriors Semantic Segmentation challenge

We present the "Visual Inductive Priors for Data-Efficient Computer Vision" challenges. We offer four challenges, where models are to be trained from scratch, and we reduce the number of training samples to a fraction of the full set. The winners of each challenge are invited to present their winning method at the VIPriors workshop presentation at ECCV 2020.

This challenge is the VIPriors Semantic Segmentation Challenge. We provide a subset of the Cityscapes dataset (MiniCity) to train on. We will evaluate all models submitted to the challenge on Cityscapes validation data.

Please note that this challenge does not allow using any pre-trained checkpoint, including any pre-trained backbone! To warrant the competitive integrity of the competition competitive participants may expect a request to share their code with the organizers for a reproducability study.

The winners of this challenge will get an opportunity to present their method at the VIPriors workshop at ECCV 2020. The organizers will contact contenders that are eligible for this opportunity after the challenges close.

Report

Data

As training data for these challenges we use subsets of publicly available datasets. We do not directly provide the data but instead expose tooling to generate the subsets from the canonical versions of the publicly available full datasets through our toolkit. The MiniCity dataset consists of a train, val and test set of 200, 100 and 200 images, respectively. Please refer to "Resources" below for details for details.

Resources

To accommodate submissions to the challenges we provide a toolkit that contains:

• Python tools for generating the appropriate training and validation data;
• documentation of the required submission format for the challenges;
• implementations of the baseline models for each challenge.

See the GitHub repository of the toolkit here.

Questions

If you have any questions, please first refer to the FAQ in the toolkit repository. If your question is not answered you can ask it in the challenge forums.
