ECNet: Effective Controllable Text-to-Image Diffusion Models

no code implementations27 Mar 2024 Sicheng Li, Keqiang Sun, Zhixin Lai, Xiaoshi Wu, Feng Qiu, Haoran Xie, Kazunori Miyata, Hongsheng Li

Secondly, to overcome the issue of limited conditional supervision, we introduce Diffusion Consistency Loss (DCL), which applies supervision on the denoised latent code at any given time step.

Ponymation: Learning 3D Animal Motions from Unlabeled Online Videos

no code implementations21 Dec 2023 Keqiang Sun, Dor Litvak, Yunzhi Zhang, Hongsheng Li, Jiajun Wu, Shangzhe Wu

We introduce Ponymation, a new method for learning a generative model of articulated 3D animal motions from raw, unlabeled online videos.

Human Preference Score v2: A Solid Benchmark for Evaluating Human Preferences of Text-to-Image Synthesis

1 code implementation15 Jun 2023 Xiaoshi Wu, Yiming Hao, Keqiang Sun, Yixiong Chen, Feng Zhu, Rui Zhao, Hongsheng Li

By fine-tuning CLIP on HPD v2, we obtain Human Preference Score v2 (HPS v2), a scoring model that can more accurately predict human preferences on generated images.

Human Preference Score: Better Aligning Text-to-Image Models with Human Preference

1 code implementation ICCV 2023 Xiaoshi Wu, Keqiang Sun, Feng Zhu, Rui Zhao, Hongsheng Li

To address this issue, we collect a dataset of human choices on generated images from the Stable Foundation Discord channel.

CGOF++: Controllable 3D Face Synthesis with Conditional Generative Occupancy Fields

no code implementations23 Nov 2022 Keqiang Sun, Shangzhe Wu, Ning Zhang, Zhaoyang Huang, Quan Wang, Hongsheng Li

Capitalizing on the recent advances in image generation models, existing controllable face image synthesis methods are able to generate high-fidelity images with some levels of controllability, e. g., controlling the shapes, expressions, textures, and poses of the generated face images.

Inverting Generative Adversarial Renderer for Face Reconstruction

no code implementations CVPR 2021 Jingtan Piao, Keqiang Sun, KwanYee Lin, Quan Wang, Hongsheng Li

Since the GAR learns to model the complicated real-world image, instead of relying on the simplified graphics rules, it is capable of producing realistic images, which essentially inhibits the domain-shift noise in training and optimization.
