Tuning-Free Inversion-Enhanced Control for Consistent Image Editing

no code implementations22 Dec 2023 Xiaoyue Duan, Shuhao Cui, Guoliang Kang, Baochang Zhang, Zhengcong Fei, Mingyuan Fan, Junshi Huang

Consistent editing of real images is a challenging task, as it requires performing non-rigid edits (e. g., changing postures) to the main objects in the input image without changing their identity or attributes.

Prefix-diffusion: A Lightweight Diffusion Model for Diverse Image Captioning

no code implementations10 Sep 2023 Guisheng Liu, Yi Li, Zhengcong Fei, Haiyan Fu, Xiangyang Luo, Yanqing Guo

While impressive performance has been achieved in image captioning, the limited diversity of the generated captions and the large parameter scale remain major barriers to the real-word application of these systems.

Masked Auto-Encoders Meet Generative Adversarial Networks and Beyond

1 code implementation CVPR 2023 Zhengcong Fei, Mingyuan Fan, Li Zhu, Junshi Huang, Xiaoming Wei, Xiaolin Wei

In this paper, we introduce a novel Generative Adversarial Networks alike framework, referred to as GAN-MAE, where a generator is used to generate the masked patches according to the remaining visible patches, and a discriminator is employed to predict whether the patch is synthesized by the generator.

Uncertainty-Aware Image Captioning

no code implementations30 Nov 2022 Zhengcong Fei, Mingyuan Fan, Li Zhu, Junshi Huang, Xiaoming Wei, Xiaolin Wei

It is well believed that the higher uncertainty in a word of the caption, the more inter-correlated context information is required to determine it.
