Box2Mask: Box-supervised Instance Segmentation via Level-set Evolution

2 code implementations3 Dec 2022 Wentong Li, Wenyu Liu, Jianke Zhu, Miaomiao Cui, Risheng Yu, Xiansheng Hua, Lei Zhang

In contrast to fully supervised methods using pixel-wise mask labels, box-supervised instance segmentation takes advantage of simple box annotations, which has recently attracted increasing research attention.

Box-supervised Instance Segmentation with Level Set Evolution

1 code implementation19 Jul 2022 Wentong Li, Wenyu Liu, Jianke Zhu, Miaomiao Cui, Xiansheng Hua, Lei Zhang

A simple mask supervised SOLOv2 model is adapted to predict the instance-aware mask map as the level set for each instance.

SP-ViT: Learning 2D Spatial Priors for Vision Transformers

1 code implementation15 Jun 2022 Yuxuan Zhou, Wangmeng Xiang, Chao Li, Biao Wang, Xihan Wei, Lei Zhang, Margret Keuper, Xiansheng Hua

Unlike convolutional inductive biases, which are forced to focus exclusively on hard-coded local regions, our proposed SPs are learned by the model itself and take a variety of spatial relations into account.

Beyond a Video Frame Interpolator: A Space Decoupled Learning Approach to Continuous Image Transition

1 code implementation18 Mar 2022 Tao Yang, Peiran Ren, Xuansong Xie, Xiansheng Hua, Lei Zhang

Most of the existing deep learning based VFI methods adopt off-the-shelf optical flow algorithms to estimate the bidirectional flows and interpolate the missing frames accordingly.

Discriminative-Generative Dual Memory Video Anomaly Detection

no code implementations29 Apr 2021 Xin Guo, Zhongming Jin, Chong Chen, Helei Nie, Jianqiang Huang, Deng Cai, Xiaofei He, Xiansheng Hua

In this paper, we propose a DiscRiminative-gEnerative duAl Memory (DREAM) anomaly detection model to take advantage of a few anomalies and solve data imbalance.

Feature Pyramid Transformer

1 code implementation ECCV 2020 Dong Zhang, Hanwang Zhang, Jinhui Tang, Meng Wang, Xiansheng Hua, Qianru Sun

Yet, the non-local spatial interactions are not across scales, and thus they fail to capture the non-local contexts of objects (or parts) residing in different scales.
