I am working on a project where I am getting a pipe as input picture. The background and lightning can vary and its hard to get the same image over and over.
I would like to get the Y position of the triangular and circular phase on the pipe.
In the PNG file you see:
Figure A: Typical source picture
Figure B-E: Different results after filtering source picture
Is there some way to recognize the phases outlined in red?
I am new to pattern recognition and can't find any good examples for this task.
Thanks
