Good morning,
I'm a student at L'école des pupilles de l'air.
I would like to know if it is posible to have any contact with you. I'm working on the subject ''Eulerian magnification of video'' and I would be enjoyed to discuss with you about your project to better understand it and to better code it again in my way

Thanks for your time
ZUANON Betty

the line is
filter_tensor=butter_bandpass_filter(lap_video_list[i],low,high,f)

Hi
I had a few questions, i couldn't find your email on your github profile.Can we please speak?

Thanks

你好，我看到你的代码里有RGB转YIQ的模块，但是实际上并没有使用这一模块，另外处理后的视频长度缩减一半，这是什么原因

Hi! I used magnify_motion("me.mp4", 0.4, 3)

and got

Traceback (most recent call last):
  File "./EVM.py", line 167, in <module>
    magnify_motion("me.mp4",3,5, 3, 22)
  File "./EVM.py", line 155, in magnify_motion
    lap_video_list=laplacian_video(t,levels=levels)

me.mp4.zip

When I run the code on a custom video of the size 440x220, I get the following error using color magnification.

When I run the same video on motion magnification, I also get an error.

It seems as though the code only works with videos of certain sizes? Is there a way for me to make the code size-independent so I can run my custom video through it? Thanks.

If i run this code with baby.mp4, my system got hanged
if i run with the low quality it is working,but i am not getting the correct output.
pls help me to solve the issue
out.zip
this is my output
