# trace.moe database dump

Direct database dump of video analysis data from trace.moe. Includes MPEG-7 color layout of each frame, detected scene change, media information and the corresponding anilist info.

This dataset can be used for various research purposes, such as:

- trace back anime scenes with a screenshot (like trace.moe does) by comparing the color layout vectors.
- find similar scenes across different anime videos
- find duplicated videos or video segments
- study scene change patterns in anime videos
- quantitative analysis of anime visual characteristics over time / across genres

No video content is included in this dataset. Metadata only.

| Dataset         | Cut-off Date | Analyzed Video | Analyzed Frames | Total Duration |

This dataset can be loaded to postgresql. You can also find the instructions in https://github.com/soruly/trace.moe and the source code for how these video are analyzed.

Notes:

- There are many different episode numbering systems. This episode number follows Anilist, which is always an integer starting with 1 and never larger than the total number of episodes. (no EP0 or EP12.5) Please refer to the file path for the original episode numbering in the source video, which may be more familiar to users.
