Semantic Diffusion Network for Semantic Segmentation

no code implementations NeurIPS 2022 Haoru Tan, Sitong Wu, Jimin Pi

We then propose a novel learnable approach called semantic diffusion network (SDN) to approximate the diffusion process, which contains a parameterized semantic difference convolution operator followed by a feature fusion module.

Augmentation Matters: A Simple-yet-Effective Approach to Semi-supervised Semantic Segmentation

1 code implementation CVPR 2023 Zhen Zhao, Lihe Yang, Sifan Long, Jimin Pi, Luping Zhou, Jingdong Wang

Differently, in this work, we follow a standard teacher-student framework and propose AugSeg, a simple and clean approach that focuses mainly on data perturbations to boost the SSS performance.

Instance-specific and Model-adaptive Supervision for Semi-supervised Semantic Segmentation

1 code implementation CVPR 2023 Zhen Zhao, Sifan Long, Jimin Pi, Jingdong Wang, Luping Zhou

Relying on the model's performance, iMAS employs a class-weighted symmetric intersection-over-union to evaluate quantitative hardness of each unlabeled instance and supervises the training on unlabeled data in a model-adaptive manner.

Beyond Attentive Tokens: Incorporating Token Importance and Diversity for Efficient Vision Transformers

1 code implementation CVPR 2023 Sifan Long, Zhen Zhao, Jimin Pi, Shengsheng Wang, Jingdong Wang

In this paper, we emphasize the cruciality of diverse global semantics and propose an efficient token decoupling and merging method that can jointly consider the token importance and diversity for token pruning.

Multimodal Utterance-level Affect Analysis using Visual, Audio and Text Features

2 code implementations2 May 2018 Didan Deng, Yuqian Zhou, Jimin Pi, Bertram E. Shi

The integration of information across multiple modalities and across time is a promising way to enhance the emotion recognition performance of affective systems.
