Cover Story: Semantic segmentation has become one of the key steps toward scene understanding, especially in autonomous driving scenarios. In the standard formulation, semantic segmentation uses only data from color cameras, which suffer significantly in dim lighting or adverse weather conditions. A solution to this problem is the use of multiple heterogeneous sensors (e.g., depth and thermal cameras or LiDARs) as the input to machine learning approaches tackling this task, allowing to cover for the shortcomings of color cameras and to extract a more resilient representation of the scene. In this work, we analyzed the current state-of-the-art deep learning methods for multimodal semantic segmentation and the datasets used to train them, collating, categorizing, and drawing similarities between them.
