The total KITTI dataset is not only for semantic segmentation, it also includes dataset of 2D and 3D object detection, object tracking, road/lane detection, scene flow, depth evaluation, optical flow and semantic instance level segmentation. MOPT unifies the distinct tasks of semantic segmentation (pixel-wise classification of 'stuff' and 'thing' classes), instance segmentation (detection and segmentation of instance-specific 'thing' classes) and multi-object tracking (detection and association of 'thing' classes over time). The KITTI (Karlsruhe Institute of Technology and Toyota Technological Institute) dataset was released in 2012, but not with semantically segmented images. Human-readable label description files in xml allow to define label names, ids, and colors. To combine RGB image and dense depth map more effectively for instance segmentation, inspired by recent multi-modal fusion models [12, 19], a sharpening mixture of experts (SMoE) fusion network is proposed based on the real-time instance segmentation network YOLACT [] to automatically learn the contribution of each modality for instance segmentation in complex scenes.
