VisDA 2022 Challenge: Domain Adaptation for Industrial Waste Sorting
Label-efficient and reliable semantic segmentation is essential for many
real-life applications, especially for industrial settings with high visual
diversity, such as waste sorting. In industrial waste sorting, one of the
biggest challenges is the extreme diversity of the input stream depending on
factors like the location of the sorting facility, the equipment available in
the facility, and the time of year, all of which significantly impact the
composition and visual appearance of the waste stream. These changes in the
data are called ``visual domains'', and label-efficient adaptation of models to
such domains is needed for successful semantic segmentation of industrial
waste. To test the abilities of computer vision models on this task, we present
the VisDA 2022 Challenge on Domain Adaptation for Industrial Waste Sorting. Our
challenge incorporates a fully-annotated waste sorting dataset, ZeroWaste,
collected from two real material recovery facilities in different locations and
seasons, as well as a novel procedurally generated synthetic waste sorting
dataset, SynthWaste. In this competition, we aim to answer two questions: 1)
can we leverage domain adaptation techniques to minimize the domain gap? and 2)
can synthetic data augmentation improve performance on this task and help adapt
to changing data distributions? The results of the competition show that
industrial waste detection poses a real domain adaptation problem, that domain
generalization techniques such as augmentations, ensembling, etc., improve the
overall performance on the unlabeled target domain examples, and that
leveraging synthetic data effectively remains an open problem. See
