What is Mix3D Semantic Segmentation?

Mix3D Semantic Segmentation is a data augmentation technique developed by researchers from RWTH Aachen University, NVIDIA, and ETH AI Center. It is designed to segment large-scale 3D scenes by balancing global scene context and local geometry. The tool creates new training samples by combining two augmented scenes, placing object instances into novel out-of-context environments. This makes it harder for models to rely solely on scene context and encourages them to infer semantics from local structures as well. By training models with Mix3D, significant performance improvements have been observed on both indoor and outdoor datasets.
