Hi,
I have a contour image of a turbocharger. I wanted to extract the efficiency map (Contour Map) from the image.
Image is attached for your reference. How should I initiate the process with matlab code.
Would be more helpful if someone could guide me how to start with either matlab or any other toolbox and link to process the image.
Thanks & regards
Raghu
