Challenge Instruction


The goal of our OOD-CV benchmark is do diagnose robustness of computer vision models to out-of-distribution shifts in the data. To achieve this goal, the benchmark consists of a fixed training set with 10 object categories (aeroplane, bus, car, train, boat, bicycle, motorplane, chair, dining table, sofa) from the PASCAL VOC 2012 and ImageNet datasets. Note that only our provided training data can be used to train a model and using outside training data is not allowed. This restriction enables us to design the test set such that each test example is subject to an out-of-distribution shift in one specific nuisance w.r.t. the training data, such as the object's 3D pose, shape, texture, context, the weather, and occlusion.

The OOD-CV challenge has three tracks. Each track will focus on one computer vision task, including image classification, object detection and 3D pose estimation. The winners of each track will be invited to contribute to an IJCV special issue. Moreover, the winners and runner-ups in each challenge track will share a prize pool of 10'000 USD.

Data and Baselines

The training data, validation data and code for the baseline models can be downloaded from this website:

The final test set will not be publicly available (see details of the evaluation process below). Note that the training set is fixed and the use any outside data is not allowed. All prize winners (i.e. winning submissions and runner-ups) will be required to either publish their code online, or send us their code privately, such that we can verify that no outside data has been used.

Benchmark Scoring

Our aim is to measure model robustness w.r.t. OOD nuisance factors. Therefore, the final benchmark scoring is data and accuracy constrained. This means, that to be valid a submission must:
1) Only use the training data that we provide. Using outside data is not allowed.
2) The model's accuracy on the I.I.D. test set must be lower than a pre-defined threshold (which is defined by the performance of a baseline model).
The final benchmark score is then measured as average performance on the held-out O.O.D. test set.

The I.I.D. accuracy thresholds are as follows:
Image Classification = 91.1 [top-1 accuracy]
Object Detection = 79.9 [mAP@50]
Pose Estimation = 68.7 [Acc@pi/6]
Each accuracy threshold was determined by training the baseline models (see paper and Github repo) five times, followed by computing the mean performance and adding three standard deviations.
