imfill or other function to make a donut from contours?
显示 更早的评论
Hello,
I am trying to make a donut from two concentric sets of contours. When I use imfill, it completely fills in the outer contour. I was wondering if there is function that will fill in the space between the two concentric contours, and leave the center of the inner contour empty. It needs to generalize to be able to handle multiple inner contours (think Swiss cheese rather than a donut) but does not necessarily need to be able to handle more than 2 nested contours. I know a way to accomplish this, but don't want to write the code if MATLAB has a function that can already do it. Any help would be appreciated. thanks!

They were probably waiting for you to post a diagram showing what you have and what you want, to make it easier to understand.
I have attached a picture of what I am trying to accomplish. Top left is the contour set, top middle is how I want it to be filled in. Top right is what I get using imfill. Bottom set is the more general case with more holes (swiss chesse). Any help would be appreciated. Thanks
