Self-supervised Document Clustering Based on BERT with Data Augment

no code implementations17 Nov 2020 Haoxiang Shi, Cen Wang

Contrastive learning is a promising approach to unsupervised learning, as it inherits the advantages of well-studied deep models without a dedicated and complex model design.

Hair Segmentation on Time-of-Flight RGBD Images

no code implementations7 Mar 2019 Yuanxi Ma, Cen Wang, Shiying Li, Jingyi Yu

Robust segmentation of hair from portrait images remains challenging: hair does not conform to a uniform shape, style or even color; dark hair in particular lacks features.

Sparse Photometric 3D Face Reconstruction Guided by Morphable Models

no code implementations CVPR 2018 Xuan Cao, Zhang Chen, Anpei Chen, Xin Chen, Cen Wang, Jingyi Yu

We present a novel 3D face reconstruction technique that leverages sparse photometric stereo (PS) and latest advances on face registration/modeling from a single image.
