You could try imclose(), followed by bwmorph('skel') to skeletonize again, if necessary. Or take a look at this Peter's edge linking code: http://www.csse.uwa.edu.au/~pk/Research/MatlabFns/#edgelink

This link isn't working, is there anywhere else this code can be viewed?

Try this:

I'm also attaching two of my edge linking demos.

[Sumit]

if minDistance <= longestGapToClose

% Draw line from this endpoint to the other endpoint.

% line([thisColumn, nearestX], [thisRow, nearestY], 'Color', 'g', 'LineWidth', 2);

h = images.roi.Line(gca, 'Color', 'r', 'Position',[thisColumn, thisRow; nearestX, nearestY]);

% You can comment out the fprintf() to speed up the overall time the process takes.

fprintf('Drawing line #%d (which is %.1f pixels long) from (%d, %d) on segment #%d to (%d, %d) on segment #%d.\n', ...

lineCounter, minDistance, thisColumn, thisRow, theLabels(k), nearestX, nearestY, theLabels(k2));

drawnow;

mask = h.createMask(rowsInImage, columnsInImage);

finalMask(mask) = true; % Burn line into output image.

% Increment the line counter.

lineCounter = lineCounter + 1;

end

end

i have encountered this error in these lines of code , can you help me?

Invalid or deleted object.

Error in images.roi.Line/getLineData

Error in images.roi.internal.mixin.CreateMask/createOpenMask

Error in images.roi.Line/createMask

Which demo did you run and what images and parameters did you use?

[Sumit]

i have used edgelinkingimage demo and images i used are from MSRA dataset
