关于视频长度和采样问题 #24
Comments
你可以把 frame_mode 改成 fps,然后修改 fps 的值,比如 0.1 就是10秒1帧这么抽取。如果要扩展帧目前只能用这个方法。 |
可以请教一下为什么最初设计时要限制8帧么?是帧数太多性能下降吗? |
对的,如果视频太长,帧数太多做pooling之后会混淆,我在最新版的论文中用了一个transformer去解决这个问题,但是代码还没有更新上来。 |
感谢解答。能问一下新版代码计划什么时候更新? |
争取这周吧,最近事情比较多 |
好的谢谢! |
已更新 |
我大致看了一下更新的代码,按我的理解现在还是只支持8帧输入么?另外能问一下新的模型权重计划什么时候更新吗?谢谢! |
把 frame mode 改成 fps, 传进去的视频 就不是8帧的 |
我知道了,train外面没有留这个接口 |
dataset.py 里面的load video 函数传一个参数,frame mode = ‘fps’ , 就可以按照帧率抽取视频帧了。 |

代码中对于每个video固定采样8个frame,
fixed_frame_number=8
。我想请教一下:
