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.

Monocular Pedestrian Orientation Estimation Based on Deep 2D-3D Feedforward

1 code implementation24 Sep 2019 Chenchen Zhao, Yeqiang Qian, Ming Yang

The 2D and 3D dimensions of pedestrians are determined from the camera captures and further utilized through two feedforward links connected to the orientation estimator.

Joint Calibration of Panoramic Camera and Lidar Based on Supervised Learning

no code implementations9 Sep 2017 Mingwei Cao, Ming Yang, Chunxiang Wang, Yeqiang Qian, Bing Wang

In view of contemporary panoramic camera-laser scanner system, the traditional calibration method is not suitable for panoramic cameras whose imaging model is extremely nonlinear.
