Can not get the file of Drop Data CSV

[shenyigang]

Thanks for your time.
I think it is a useful program for analyzing the droplet in the microfluidic channel. However, when I ran the code, it shows some problem, I could not get the output file of Drop Data CSV (Just sin data), does the analyzing movie file have a limitation, I took a video ( 30s ) for running the code. If you can help me solve this problem, that will be great.

Sorry about that, the opencv library updated and broke some of the code. Try pulling my last commit and running this again. Let me know if that fixes it.

I downloaded the last commit, it works so well. Thanks for your kind help.

@chrizrodz you need to fix the version number of OpenCV required as a dependency. I use pipenv (https://pipenv.readthedocs.io/en/latest/) for this.
