PONet: Robust 3D Human Pose Estimation via Learning Orientations Only

no code implementations21 Dec 2021 Jue Wang, Shaoli Huang, Xinchao Wang, DaCheng Tao

Conventional 3D human pose estimation relies on first detecting 2D body keypoints and then solving the 2D to 3D correspondence problem. Despite the promising results, this learning paradigm is highly dependent on the quality of the 2D keypoint detector, which is inevitably fragile to occlusions and out-of-image absences. In this paper, we propose a novel Pose Orientation Net (PONet) that is able to robustly estimate 3D pose by learning orientations only, hence bypassing the error-prone keypoint detector in the absence of image evidence.

Based on this observation, our method applies a series of directional filters at different orientations to the input image, and estimates an accurate Radon transform of the blur kernel from each filtered image.

Supervised Semantic Gradient Extraction Using Linear-Time Optimization

no code implementations CVPR 2013 Shulin Yang, Jue Wang, Linda Shapiro

This paper proposes a new supervised semantic edge and gradient extraction approach, which allows the user to roughly scribble over the desired region to extract semantically-dominant and coherent edges in it.

Unsupervised Template Learning for Fine-Grained Object Recognition

no code implementations NeurIPS 2012 Shulin Yang, Liefeng Bo, Jue Wang, Linda G. Shapiro

It differs from recognition of basic categories, such as humans, tables, and computers, in that there are global similarities in shape or structure shared within a category, and the differences are in the details of the object parts.

Avoiding False Positive in Multi-Instance Learning

no code implementations NeurIPS 2010 Yanjun Han, Qing Tao, Jue Wang

In multi-instance learning, there are two kinds of prediction failure, i. e., false negative and false positive.
