LinkTo-Anime
收藏资源简介:
LinkTo-Anime是一个专为2D动画光学流预测而设计的高质量数据集,它通过3D模型渲染生成,包含395个视频序列,共计24,230个训练帧,720个验证帧和4,320个测试帧。该数据集提供了丰富的注释,包括正向和反向光学流、遮挡掩模和Mixamo骨骼。数据集的图像与2D动画生产中的图像特性相符,具有高分辨率和精细的字符细节,以及多视角的字符渲染,以实现更高的多样性。数据集的构建旨在解决现有光学流数据集主要关注现实世界模拟或合成人体运动,而很少针对动画角色运动的问题。
LinkTo-Anime is a high-quality dataset specifically designed for 2D animation optical flow prediction. It is generated via 3D model rendering and consists of 395 video sequences, with a total of 24,230 training frames, 720 validation frames, and 4,320 test frames. This dataset provides comprehensive annotations including forward and backward optical flows, occlusion masks, and Mixamo skeletons. The images in this dataset match the visual characteristics of images used in 2D animation production, boasting high resolution and fine-grained character details, as well as multi-view character rendering to enable greater diversity. This dataset was constructed to address the issue that most existing optical flow datasets primarily focus on real-world simulated or synthetic human motion, while rarely targeting animated character motion.
