Hello 🙂 I just purchased OpenMV to solve the project using lip detection. Looking for a way, I found OpenMV provides ‘find\_blobs’ function instead findContour.  
is it possible to use ‘find\_blobs’ to find lip? If it’s not, how could I solve that problem?  
and I also found the way to add ‘c code file’ in OpenMV project. so is this way can possibly do it??  
(I attach the example pictures)

I look forward to your response. Thank you!

Hi, we don’t have a built-in haar cascade for this. I don’t know how to quite use our Haar Cascade conversion script to convert the OpenCV lip cascade.

Sorry, I don’t know how you can easily do this with the system right now. It’s not out of it’s processing power. But, the right algorithm needs to be ported.
