Has anyone ever done any object tracking at night when the object to be tracked is just a light?

I'm building an application that looks for trains traveling down a railroad track. The track is on an angle relative to the camera. When trains are coming toward the camera, with the bright light of the lead locomotive, contour detection and subsequent tracking works really well.

However when the train is going in the other direction (quartering away from the camera) the lead locomotive's light is not as bright....and the tracker loses the object after just a few frames.....which is an insufficient amount of data for me to confirm there is a train there.

I've played with increasing the contrast, as well as different Background Subtraction algorithms, but none of those experiments resulted in better results.

Does this type of issue ring true with anyone here?

Thanks!

Jim

Unfortunately, yes, I've already tried other tracking methods. (I'll re-try MEDIANFLOW, though, based on your comment.)
