Live2K
收藏资源简介:
Live2K数据集是由电子科技大学、欧珀研究院和香港理工大学联合构建的首个面向Live Photo重选与增强任务的大规模真实世界数据集,共包含2,042个Live Photo样本,涵盖人像、建筑、自然景观和室内场景等多种类别。该数据集使用iPhone 16 Pro和OPPO Find X8 Pro两款智能手机采集,每样本包含一张高质量封面图像及其对应的视频序列,封面图像分辨率分别为4032×3024和4096×3072,视频帧分辨率分别为1920×1440和1728×1296,通过分组采集策略构建了视觉相似但非相同的图像组以支持跨实例引导。数据集构建过程通过SIFT算法进行像素级对齐和视角校正,最终形成包含训练对和测试对的配对数据,旨在解决智能手机Live Photo中封面图像与视频帧之间存在分辨率、色彩保真度和动态范围质量差距的问题,为Live Photo封面帧重选与增强研究提供基准支持。
The Live2K dataset is the first large-scale real-world dataset dedicated to the tasks of Live Photo re-selection and enhancement, jointly constructed by the University of Electronic Science and Technology of China, OPPO Research Institute, and The Hong Kong Polytechnic University. It comprises a total of 2,042 Live Photo samples, covering various categories such as portraits, architecture, natural landscapes, and indoor scenes. This dataset was collected using two smartphone models: iPhone 16 Pro and OPPO Find X8 Pro. Each sample contains a high-quality cover image and its corresponding video sequence, with the cover images having resolutions of 4032×3024 and 4096×3072 respectively, and the video frames having resolutions of 1920×1440 and 1728×1296 correspondingly. A grouped collection strategy was employed to create visually similar but non-identical image groups to support cross-instance guidance. During the dataset construction process, pixel-level alignment and perspective correction were performed using the SIFT algorithm, ultimately yielding paired data consisting of training pairs and test pairs. This dataset aims to address the gaps in resolution, color fidelity, and dynamic range quality between the cover image and video frames in smartphone Live Photos, and provide benchmark support for research on Live Photo cover frame re-selection and enhancement.
数据集简介
Live2K 是一个用于“Live Photo 封面帧重选与增强(LPRE)”任务的真实世界数据集,由电子科技大学计算机视觉实验室(CVL-UESTC)构建,相关论文被 ECCV 2026 接收。
核心任务
- LPRE 任务:给定用户重新选择的低质量帧、其相邻视频帧以及原始高质量封面图像作为参考,目标是重建一张高质量替换封面帧,提升细节、色彩和动态范围。
数据集规模与构成
- 规模:包含 2,042 张 Live Photos。
- 数据结构:每个 Live Photo 样本为一个子文件夹,包含:
gt.png:高质量目标帧。ref.png:原始高质量封面图像(参考)。lq_sequence/:9 张低质量相邻视频帧(按文件名时间顺序排序,均为.png格式)。
