Extracting Correct Boundaries from Segment Borders

Hello

I have a question concerning image segmentation border extraction. I have created a function that uses bwboundaries() and plots the segmented objects on a black image. The problem is that the edges are used wrongly sometimes for the creation of a region.

Here you can see an example

1. Primary Segmentation borders (all together)

2. Using my function and plotting 1st Object

3. Using my Function and plotting 2nd Object

From the Images you can see that the problem occurs in the 3rd Image that an object (polygon) is creates based on the large polygon and not on the small one ! I need to calculate some statistical parameters for every object in the image and this problem leads to the creation of wrong data (as wrong polygon in considered).

Is there any way to overcome the problem ?

Thanks in advance '!
