I've a image with a circular object within it. I am interested only in the
circular object for further analysis. I've tried several approaches to get the
pixel for that circular object. The first approach executed was to equate every
matrix outside the circular object to zero but I had a concern, i couldn't zero
the edges since my original picture was in square. My other approach is trying
to write a matlab code that will extract the circular object from the image but
I didn't know how.
I'll appreciate if anyone can be of help.
I look forward to your reply
Image analysis of circular object

u can use image morphing related operations like image dilation and eroding,
can also try functions bwtraceboundary and bwboundaries, inbuilt in
MATLAB...

Thanks for your mail. My matlab doesn't have these function. Can you advice on
another approach? or do I need to activate something in matlab to use this
function

Hi,
"Identifying Round Objects" in MATLAB demos could be useful for your
application,
You can try it...
Good Luck.
