The image segmentation algorithm that you used to get that binary image is poor. You should improve it. Only once you can get a good binary image can you call regionprops and get meaningful data out. You're not at that point yet. Go here for "car detection" algorithms: http://iris.usc.edu/Vision-Notes/bibliography/contents.html Sorry, we can't help with your algorithm selection or implementation/development.

Once you have created a mask that corresponds to only the object, use regionprops() with the 'Area' option.

There are blobs in there with areas 1, 2, or 3 as well as some very very large areas of thousands of pixels. I don't understand why having a blob with area 3 is unexpected for you.
