Instance Segmentation With Mask-Supervised Polygonal Boundary Transformers

no code implementations CVPR 2022 Justin Lazarow, Weijian Xu, Zhuowen Tu

In this paper, we present an end-to-end instance segmentation method that regresses a polygonal boundary for each object instance.

Pose Recognition with Cascade Transformers

2 code implementations CVPR 2021 Ke Li, Shijie Wang, Xiang Zhang, Yifan Xu, Weijian Xu, Zhuowen Tu

Here we utilize the encoder-decoder structure in Transformers to perform regression-based person and keypoint detection that is general-purpose and requires less heuristic design compared with the existing approaches.

Co-Scale Conv-Attentional Image Transformers

9 code implementations ICCV 2021 Weijian Xu, Yifan Xu, Tyler Chang, Zhuowen Tu

In this paper, we present Co-scale conv-attentional image Transformers (CoaT), a Transformer-based image classifier equipped with co-scale and conv-attentional mechanisms.

Line Segment Detection Using Transformers without Edges

2 code implementations CVPR 2021 Yifan Xu, Weijian Xu, David Cheung, Zhuowen Tu

In this paper, we present a joint end-to-end line segment detection algorithm using Transformers that is post-processing and heuristics-guided intermediate processing (edge/junction/region detection) free.

Constellation Nets for Few-Shot Learning

1 code implementation ICLR 2021 Weijian Xu, Yifan Xu, Huaijin Wang, Zhuowen Tu

The success of deep convolutional neural networks builds on top of the learning of effective convolution operations, capturing a hierarchy of structured features via filtering, activation, and pooling.

Guided Variational Autoencoder for Disentanglement Learning

no code implementations CVPR 2020 Zheng Ding, Yifan Xu, Weijian Xu, Gaurav Parmar, Yang Yang, Max Welling, Zhuowen Tu

We propose an algorithm, guided variational autoencoder (Guided-VAE), that is able to learn a controllable generative model by performing latent representation disentanglement learning.
