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 ( , 和 )。在本文中，我们使用Inter4K来解决帧上采样和插值问题。Inter4K通过包含各种1,000的5秒视频，为所有视频提供标准化的UHD分辨率和60 fps。场景之间的差异源于设备 (例如，专业的4k摄像机或电话)，照明条件，运动，动作或对象的变化。数据集分为用于培训的800视频，用于验证的100视频和用于测试的100视频。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.
