close lines after edge detection
显示 更早的评论
Hi all, After edge detection and adding some circular object, I like to close the lines and fill each area. this is an example : http://i48.tinypic.com/35hq0cg.jpg
is there a way to close the lines without dilation or morfological operations? those would modify the accuracy of the detection.

Other options would be convex hull or restricted convex hull, or Sean's shrink wrap: http://www.mathworks.com/matlabcentral/fileexchange/29175-shrinkwrap

Hi.
Did you manage to solve your issue? Image Analyst, is there a way to apply the convex hull to pixels?

Using a convex hull may not always be a good choice - it won't give the right shape in some situations. For a banana shape, it convex hull would give a D-shape. One must really look at the image and not just make blanket generalizations.

Image Analyst. I want to apply convex hull to a closed contour shape. Thus, the convex hull shape is more or less defined when applied to a closed contour. Isn't it?

The example where the line leaves a gap: where should it attach to the main body? If the "accuracy of the detection" is an issue, every choice is wrong, unless there is external information available.
