How to separate connected image objects

I would like to separate the two connected image objects that represent a music notehead. I wouldn't mind if the line above the notehead would be deleted/lost as I am calculating the centroid of the notehead to recognise the type of the note.

Thank you.

There are two approaches you can take here, either you write a script that changes the pixel values for the line given you know the coordinates of the line, which might take a long time. The other (slightly more hacky) approach is to you a some software like MS paint or paintbrush on mac to color over the line you don't want, then you can re-import that image back into Matlab, threshold it again to make a binary image and do all the processing you would like.
