Hello dear community,

I made vidoes to understand the flow better in a shear chamber.
Already converting the images in grayframes, I tried to analyse them in Matlab. But it didn' work that fine.
So, I though about filtering the pink color. See the image below.



The problem is I have no idea how to do this:(!
I would be really grateful about any help, because I really work since some days on it, but can not get a good solution!

Thank you very much!!!!!!!!!!!!!!!
