有没有检索系统？
我正在寻找一个视频检索系统，其代码很容易获得，以便我可以检查它。此外，我正在寻找有关它的任何相关文档。
该应用程序将在本地运行。我将有一个视频的本地文件夹，所以我不需要数据库。语言可以是 C++、C 或 Java。
基本上，当我运行该应用程序时，我应该能够从计算机的本地存储中选择视频。现在，应用程序应该在我的视频“数据库”中找到类似的视频并显示它们（最好还给我播放它们的选项）
I am looking for a video retrieval system whose code is readily available so that I can examine it. Moreover, I am looking for any relevant documentation about it.
The app will run locally. I will have a local folder of video, so i do not need a database. The language can be C++,C, or Java.
Basically, when i run the app, i should be able to select a video from the local storage of my computer. Now, the app should find similar videos in my "database" of videos and display them (preferably also give me the option to play them)

由于视频是一系列帧（图像），也许您可以提取一些帧并使用 phash。
据我了解，您想要使用的技术是视频指纹，但这不是一件容易的任务，因为您需要提取并保存每个视频的信息才能搜索它。
据我所知，没有任何开源库可供您使用...也许您可以向某些商业提供商提供一份试用许可证进行测试。
Since a video is a sequence of frames (images) maybe you could extract some frames and compared them using phash.
As I understand the technique you want to use is Video fingerprinting, but this is not an easy task, since you need to extract and save information for every video in order to search it.
As far as I know there aren't any opensource libraries you can use... maybe you can bug some commercial provider one trial license to test.
