This is the KITTI semantic segmentation benchmark. It consists of 200 semantically annotated train as well as 200 test images corresponding to the KITTI Stereo and Flow Benchmark 2015. The data format and metrics are conform with The Cityscapes Dataset.
The data can be downloaded here:
Note: On 12.04.2018 we have fixed several annotation errors in the dataset, please download the dataset again if you have an old version.
Our evaluation table ranks all methods according to the PASCAL VOC intersection-over-union metric (IoU). IoU = TP/(TP+FP+FN), where TP, FP, and FN are the numbers of true positive, false positive, and false negative pixels, respectively. Like in cityscapes we also use an instance-level intersection over union iIoU = iTP/(iTP+FP+iFN). In contrast to the standard IoU measure, iTP and iFN are computed by weighting the contribution of each pixel by the ratio of the class’ average instance size to the size of the respective ground truth instance.
- IoU class:  Intersection over Union for each class IoU=TP/(TP+FP+FN)
- iIoU class:    Instance Intersection over Union iIoU=iTP/(iTP+FP+iFN)
- IoU category:   Intersection over Union for each category IoU=TP/(TP+FP+FN)
- iIoU category:     Instance Intersection over Union for each category iIoU=iTP/(iTP+FP+iFN)
- Laser Points: Method uses point clouds from Velodyne laser scanner
- Depth: Method uses depth from stereo.
- Video: Method uses 2 or more temporally adjacent images
- Additional training data: Use of additional data sources for training (see details)
