Vehicles, systems and methods for automatically detecting a state of signal lights of a vehicle

A vehicle comprising:

• one or more processors;
• and
• a non-transitory memory module storing computer-readable instructions configured to cause the one or more processors to:
• receive a first image of a road vehicle and receiving a second image of the vehicle, wherein the second image is later in time from the first image;
• generate a warped image from one of the first image and the second image, wherein the warped image has individual pixels of one of the first image and the second image that are shifted to locations of corresponding pixels of the other of the first image and the second image such that the individual pixels of the warped image are aligned with the individual pixels of the other of the first image and the second image;
• generate a difference image from the warped image and one of the first image and the second image;
• and
• determine, using a classifier module, a probability of a state of vehicle signal lights.
