Denoising Diffusion Semantic Segmentation with Mask Prior Modeling

no code implementations2 Jun 2023 Zeqiang Lai, Yuchen Duan, Jifeng Dai, Ziheng Li, Ying Fu, Hongsheng Li, Yu Qiao, Wenhai Wang

In this paper, we propose to ameliorate the semantic segmentation quality of existing discriminative approaches with a mask prior modeled by a recently-developed denoising diffusion generative model.

Bypassing Logits Bias in Online Class-Incremental Learning with a Generative Framework

no code implementations19 May 2022 Gehui Shen, Shibo Jie, Ziheng Li, Zhi-Hong Deng

In our framework, a generative classifier which utilizes replay memory is used for inference, and the training objective is a pair-based metric learning loss which is proven theoretically to optimize the feature space in a generative way.

A Sinogram Inpainting Method based on Generative Adversarial Network for Limited-angle Computed Tomography

no code implementations10 Mar 2019 Ziheng Li, Wenkun Zhang, Linyuan Wang, Ailong Cai, Ningning Liang, Bin Yan, Lei LI

Limited-angle computed tomography (CT) image reconstruction is a challenging reconstruction problem in the fields of CT. With the development of deep learning, the generative adversarial network (GAN) perform well in image restoration by approximating the distribution of training sample data.
