Threshold-adaptive Unsupervised Focal Loss for Domain Adaptation of Semantic Segmentation

1 code implementation23 Aug 2022 Weihao Yan, Yeqiang Qian, Chunxiang Wang, Ming Yang

In stage one, we design a threshold-adaptative unsupervised focal loss to regularize the prediction in the target domain, which has a mild gradient neutralization mechanism and mitigates the problem that hard samples are barely optimized in entropy-based methods.

Restricted Deformable Convolution based Road Scene Semantic Segmentation Using Surround View Cameras

no code implementations2 Jan 2018 Liuyuan Deng, Ming Yang, Hao Li, Tianyi Li, Bing Hu, Chunxiang Wang

Finally, an RDC based semantic segmentation model is built; the model is trained for real-world surround view images through a multi-task learning architecture by combining real-world images with transformed images.
