[0122] 1. Experimental data set
[0123] The method proposed in the present invention is tested on the commonly used unsupervised adaptive dataset GTA5-Cityscapes, where the synthetic dataset GTA5 is used as the source domain and the real dataset Cityscapes is used as the target domain. Models are evaluated on the Cityscapes validation set.
[0124] GTA5: The synthetic dataset GTA5 contains 24966 synthetic images with a resolution of 1914×1052 and the corresponding ground-truth. These composite images were collected from a cityscape video game based on the city of Los Angeles. The automatically generated ground-truth contains 33 categories. The methods experimented on GTA5-Cityscapes generally only consider the 19 categories compatible with the Cityscapes dataset, and the present invention is no exception.
[0125] Cityscapes: As a dataset collected from the real world, Cityscapes provides 3975 images with fine segmentation annotations. The training set contains 2975 image...
