I am a newbie in Image Processing using Matlab. I have been trying to follow this thread - http://www.mathworks.com/matlabcentral/newsreader/view_thread/264686
. I have been successful in doing edge detection and also generating the PixelList arrays. I get three arrays after I run the code. I have attached the code and the image for your reference.
I am not able to identify the coordinates of a particular point on the image( of a bubble) using the data I have in those arrays. How should I proceed in order to get the curvature of the boundary? I couldn't follow the thread that I posted before clearly. It would be helpful if someone explains it better since I am a newbie.
Thanks in advance!
