Training-Free Semantic Video Composition via Pre-trained Diffusion Model

no code implementations17 Jan 2024 Jiaqi Guo, Sitong Su, Junchen Zhu, Lianli Gao, Jingkuan Song

Therefore, we propose a training-free pipeline employing a pre-trained diffusion model imbued with semantic prior knowledge, which can process composite videos with broader semantic disparities.

CUCL: Codebook for Unsupervised Continual Learning

1 code implementation25 Nov 2023 Chen Cheng, Jingkuan Song, Xiaosu Zhu, Junchen Zhu, Lianli Gao, HengTao Shen

To address this issue, after analyzing the phenomenon and identifying the lack of diversity as a vital factor, we propose a method named Codebook for Unsupervised Continual Learning (CUCL) which promotes the model to learn discriminative features to complete the class boundary.

MobileVidFactory: Automatic Diffusion-Based Social Media Video Generation for Mobile Devices from Text

no code implementations31 Jul 2023 Junchen Zhu, Huan Yang, Wenjing Wang, Huiguo He, Zixi Tuo, Yongsheng Yu, Wen-Huang Cheng, Lianli Gao, Jingkuan Song, Jianlong Fu, Jiebo Luo

In the basic generation, we take advantage of the pretrained image diffusion model, and adapt it to a high-quality open-domain vertical video generator for mobile devices.
