Claim 18:
19. A method for determining a location of a trailer in an image, the method comprising:
obtaining, by a controller comprising at least one microprocessor, at least one real-time image captured by a vehicle camera;
processing, by the at least one microprocessor, the at least one real-time image to obtain a feature patch describing the at least one real-time image;
performing, by the at least one microprocessor, a convolution of the feature patch and each filter from a set of filters with the filters of the set of filters being based on data representative of known trailers, the convolution of the feature patch and each filter from the set of filters comprising an integral of a product of the feature patch and the filter after at least one of the feature patch or the filter is reversed and shifted;
determining, by the at least one microprocessor, a location of a trailer in the at least one real-time image based on the convolution between the feature patch and each filter from the set of filters, comprising using a voting process to identify a region of pixels or a single pixel in the at least one real-time image with a greatest correlation to the location of the trailer using each filter; and
at least one of sending, by the at least one microprocessor, the determined trailer location to a vehicle display for displaying the determined location of the trailer, or using, by the at least one microprocessor, the determined location of the trailer in a trailer assist operation.
