Completion of Discontinuous Lines

I used imabsdiff in order to compute the absolute difference of two images of moving car. I then used im2bw to get the boundary/edge of the car. Now I would like to use imfill(I,'holes') in order to define the entire car. The problem is that the line that defines the car edge is not continuous. How can I complete the lines?

Try imclose() to close the gaps.
