Inter4K

用于基准上采样方法的视频数据集。Inter4K包含来自在线资源的1,000个超高分辨率视频，每秒60帧 (fps)。数据集提供标准的视频分辨率在超高清 (UHD/4K)，四高清 (QHD/2K)，全高清 (FHD/1080p)，(标准) 高清 (HD/720p)，四分之一的全高清 (qHD/520p) 和9分之1的全高清 (nHD/360p)。对于每种分辨率，我们使用60、50、30、24和15 fps的帧速率。基于此标准化，可以针对不同的缩放尺寸进行超分辨率和帧插值测试 (

A video dataset for benchmarking upsampling methods. Inter4K consists of 1,000 ultra-high-resolution videos sourced from online platforms, with an initial frame rate of 60 frames per second (fps). The dataset provides standard video resolutions including Ultra High Definition (UHD/4K), Quad High Definition (QHD/2K), Full High Definition (FHD/1080p), (Standard) High Definition (HD/720p), Quarter Full High Definition (qHD/520p), and Ninth Full High Definition (nHD/360p). For each resolution, we adopt frame rates of 60, 50, 30, 24, and 15 fps. Based on this standardization, super-resolution and frame interpolation tests can be conducted for different scaling dimensions (, and ). In this work, we utilize Inter4K to address frame upsampling and interpolation problems. Inter4K provides all videos with standardized UHD resolution and 60 fps, containing 1,000 5-second videos with diverse content. The variations between scenes stem from different capture devices (e.g., professional 4K cameras or smartphones), lighting conditions, motion, actions, or object changes. The dataset is split into 800 videos for training, 100 videos for validation, and 100 videos for testing.
