Claim 14:
15. A method of training a machine learning model to undertake automated license plate recognition, the method comprising:
pre-training a text-adapted vision transformer on a plurality of image-text pairs, wherein the image-text pairs comprise images or video frames of real-life objects comprising text and an annotation of the text;
training the text-adapted vision transformer on a plate dataset comprising a plurality of real plate-text pairs, wherein the real plate-text pairs comprise images or video frames of real-life license plates and an annotated license plate number associated with each of the real-life license plates; and
further training the text-adapted vision transformer on artificially-generated plate-text pairs, wherein the artificially-generated plate-text pairs comprise images of non-real license plates artificially generated by a latent diffusion model and a non-real license plate number associated with each of the non-real license plates.
