Abstract: This paper performs comprehensive analysis on datasets for occlusion-aware face segmentation, a task that is crucial for many downstream applications. The collection and annotation of such datasets are time-consuming and labor-intensive. Although some efforts have been made in synthetic data generation, the naturalistic aspect of data remains less explored. In our study, we propose two occlusion generation techniques, Naturalistic Occlusion Generation (NatOcc), for producing high-quality naturalistic synthetic occluded faces; and Random Occlusion Generation (RandOcc), a more general synthetic occluded data generation method. We empirically show the effectiveness and robustness of both methods, even for unseen occlusions. To facilitate model evaluation, we present two high-resolution real-world occluded face datasets with fine-grained annotations, RealOcc and RealOcc-Wild, featuring both careful alignment preprocessing and an in-the-wild setting for robustness test. We further conduct a comprehensive analysis on a newly introduced segmentation benchmark, offering insights for future exploration.

Data Generation

Example script to generate NatOcc dataset

bash NatOcc.sh

Example script to generate RandOcc dataset

bash RandOcc.sh

Please modify/create the configs file in /configs accordingly.

• RANDOCC : Choose between NatOcc or RandOcc. If False, NatOcc mode.
• SOT : Specifies whether to use colour transfer via Sliced Optimal Transport
• ROTATE_AROUND_CENTER : Rotate hands such that fingers always pointing toward the face.
• OCCLUSION_MASK : If True, mask of occlussion will be saved. (For RainNet)
