how to fill the binary image..?

http://owaisayub.wordpress.com/2013/02/15/parking-jpg/

I am doing a project on car parking. The image on this link is the result after edge detection. I want to fill the whole area of the car, i.e white. and leave the outer region black.

Try

filledImage = imfill(edgeImage, 'holes');

You might have to call imclose() to close gaps.
