Evaluation of Text-to-Video Generation Models: A Dynamics Perspective

1 code implementation1 Jul 2024 Mingxiang Liao, Hannan Lu, Xinyu Zhang, Fang Wan, Tianyu Wang, Yuzhong Zhao, WangMeng Zuo, Qixiang Ye, Jingdong Wang

For this purpose, we establish a new benchmark comprising text prompts that fully reflect multiple dynamics grades, and define a set of dynamics scores corresponding to various temporal granularities to comprehensively evaluate the dynamics of each generated video.

FaceScore: Benchmarking and Enhancing Face Quality in Human Generation

1 code implementation24 Jun 2024 Zhenyi Liao, Qingsong Xie, Chen Chen, Hannan Lu, Zhijie Deng

Targeting addressing such an issue, we first assess the face quality of generations from popular pre-trained DMs with the aid of human annotators and then evaluate the alignment between existing metrics with human judgments.

Two-Stream Networks for Object Segmentation in Videos

no code implementations8 Aug 2022 Hannan Lu, Zhi Tian, Lirong Yang, Haibing Ren, WangMeng Zuo

The compact instance stream effectively improves the segmentation accuracy of the unseen pixels, while fusing two streams with the adaptive routing map leads to an overall performance boost.

Component Divide-and-Conquer for Real-World Image Super-Resolution

1 code implementation ECCV 2020 Pengxu Wei, Ziwei Xie, Hannan Lu, Zongyuan Zhan, Qixiang Ye, WangMeng Zuo, Liang Lin

Learning an SR model with conventional pixel-wise loss usually is easily dominated by flat regions and edges, and fails to infer realistic details of complex textures.

Blind Super-Resolution With Iterative Kernel Correction

3 code implementations CVPR 2019 Jinjin Gu, Hannan Lu, WangMeng Zuo, Chao Dong

In this paper, we propose an Iterative Kernel Correction (IKC) method for blur kernel estimation in blind SR problem, where the blur kernels are unknown.
