How to extract the license plate region from the image of cars

[Eater]

HI, I want to extract the license plate region from the image of cars with vision assistant. I try to adjust the threshold value, remove small objects. But i still cannot get the perfect license plate region. I have attached 4 images that i am working now. I hope someone can help me to extract that region. Really thanks.

Hello, I'm trying to do the same thing, using IMAQ detect rectangles, and it's only working on a few images. Can anyone tell me why?

I'm attaching the vi.

I'm not near a PC with LabVIEW at the moment. But I'll give the thread a free bump.
