Preliminary Pore Edge Detection via Mathematica
Hi everyone, this is going to be a brief update on something that I’ve been working on the side.
I’ll be showing pore detection using color subtraction and Canny edge detection. All code was written in Mathematica.
First up, color subtraction:
Depending on image brightness, this method can fairly accurately pick up inner pores. Of course, there’s always parameter optimization that needs be to done in order to reduce noise and increase accuracy of results.
Next up, Canny edge detection:
While not as accurate at finding inner pores, this method covers almost all of the pores in an image.
I’m playing around with other algorithms too, mainly Sobel and Shen-Castan. I don’t have anything pretty (yet) but I’ll be sure to post an update when I have more to show.
