Dear Friends i want to fit a curve to my image titled original so that it may look like image titled final but the problem is i cant fit the desired curved , i tried many methods but the problem is the centroids are not ordered correctly.... the fitting starts at the middle and expands upwards then downward.... any ideas to correct centroids or fit curve without the need to correct centroid points?

Use bwconvhull(), then followup with bwboundaries().
