A Better Way to Threshold Vehicle Object?

hi there,

I tried tools in imageJ, such as auto-threshold,
background substract, etc. to threshold vehicle object
from image.

Since the vehicle object itself isn't cosnsistently
shaded, the result of threshold process is not
perfect---that the object is not with continuous
outline.

I wonder if there is other better way to extract such
object more efficiently and more accurately? or I need
to go further deeper to code particular Java algorithm
to deal with pixel directly?

From the link, you could see the original image in the
bottom and result after thresholding at the top,

thanks your time,

Michael,
