Improving Robustness for Pose Estimation via Stable Heatmap Regression

Yumeng Zhang, Li Chen, Yufeng Liu +3

Deep learning methods have achieved excellent performance in pose estimation, but the lack of robustness causes the keypoints to change drastically between similar images. In view…

Cascade Image Matting with Deformable Graph Refinement

Zijian Yu, Xuhui Li, Huijuan Huang +2

Image matting refers to the estimation of the opacity of foreground objects. It requires correct contours and fine details of foreground objects for the matting results. To better…

Adaptive Wasserstein Hourglass for Weakly Supervised Hand Pose Estimation from Monocular RGB

Yumeng Zhang, Li Chen, Yufeng Liu +2

Insufficient labeled training datasets is one of the bottlenecks of 3D hand pose estimation from monocular RGB images. Synthetic datasets have a large number of images with precise…

MetaAdvDet: Towards Robust Detection of Evolving Adversarial Attacks

Chen Ma, Chenxu Zhao, Hailin Shi +3

Deep neural networks (DNNs) are vulnerable to adversarial attack which is maliciously implemented by adding human-imperceptible perturbation to images and thus leads to incorrect p…
