Deep Hierarchical Semantic Segmentation

3 code implementations CVPR 2022 Liulei Li, Tianfei Zhou, Wenguan Wang, Jianwu Li, Yi Yang

In this paper, we instead address hierarchical semantic segmentation (HSS), which aims at structured, pixel-wise description of visual observation in terms of a class hierarchy.

Regional Semantic Contrast and Aggregation for Weakly Supervised Semantic Segmentation

1 code implementation CVPR 2022 Tianfei Zhou, Meijie Zhang, Fang Zhao, Jianwu Li

Particularly, we propose i) semantic contrast to drive network learning by contrasting massive categorical object regions, leading to a more holistic object pattern understanding, and ii) semantic aggregation to gather diverse relational contexts in the memory to enrich semantic representations.

Group-Wise Learning for Weakly Supervised Semantic Segmentation

1 code implementation journal 2021 Tianfei Zhou, Liulei Li, Xueyi Li, Chun-Mei Feng, Jianwu Li, Ling Shao

The framework explicitly encodes semantic dependencies in a group of images to discover rich semantic context for estimating more reliable pseudo ground-truths, which are subsequently employed to train more effective segmentation models.

Quality-Aware Memory Network for Interactive Volumetric Image Segmentation

1 code implementation20 Jun 2021 Tianfei Zhou, Liulei Li, Gustav Bredell, Jianwu Li, Ender Konukoglu

The proposed network has two appealing characteristics: 1) The memory-augmented network offers the ability to quickly encode past segmentation information, which will be retrieved for the segmentation of other slices; 2) The quality assessment module enables the model to directly estimate the qualities of segmentation predictions, which allows an active learning paradigm where users preferentially label the lowest-quality slice for multi-round refinement.

Group-Wise Semantic Mining for Weakly Supervised Semantic Segmentation

1 code implementation9 Dec 2020 Xueyi Li, Tianfei Zhou, Jianwu Li, Yi Zhou, Zhaoxiang Zhang

We formulate WSSS as a novel group-wise learning task that explicitly models semantic dependencies in a group of images to estimate more reliable pseudo ground-truths, which can be used for training more accurate segmentation models.

DTDN: Dual-task De-raining Network

1 code implementation21 Aug 2020 Zheng Wang, Jianwu Li, Ge Song

Removing rain streaks from rainy images is necessary for many tasks in computer vision, such as object detection and recognition.

Motion-Attentive Transition for Zero-Shot Video Object Segmentation

1 code implementation9 Mar 2020 Tianfei Zhou, Shunzhou Wang, Yi Zhou, Yazhou Yao, Jianwu Li, Ling Shao

In this paper, we present a novel Motion-Attentive Transition Network (MATNet) for zero-shot video object segmentation, which provides a new way of leveraging motion information to reinforce spatio-temporal object representation.

Less Memory, Faster Speed: Refining Self-Attention Module for Image Reconstruction

no code implementations20 May 2019 Zheng Wang, Jianwu Li, Ge Song, Tieling Li

Self-attention (SA) mechanisms can capture effectively global dependencies in deep neural networks, and have been applied to natural language processing and image processing successfully.
