Merging/connecting blobs that belong to same object

I am doing background subtraction and trying to extract the foreground object(humans). The problem is that when i am trying to crop the foreground object, due to some gape in the objects they are cropped as several blobs and not one. How can i merge/connect blobs that belong to same object but are disconnected due to some gape in the binary image. I am attaching some image to make my point clear.

You could find the centroids of all blobs and then burn a line between the centroids to connect all the blobs with a line. See attached demo.
