I have been using a code I found on the Matlab community to calculate the contact angle of a droplet on a solid surface. The code works well in detecting almost all contact angles, but I have encountered an error when trying to determine the contact angle of a sessile droplet with the cannula still in place. The issue is that the code is unable to determine the contour of the droplet for the calculation of the contact angle. How can I separate the cannula from the droplet profile in order to calculate the contact angle accurately?

Is the cannula always in the same place? Then just mask it out.

See attached mask that I forgot to include last time.
