Abstract
A system for classifying a road crossing intention of a pedestrian includes a processor including a pretrained image encoder generating an image embedding based upon an input image. The system further includes a remote server receiving the image embedding. The remote server device further references a plurality of pretrained image and text embeddings each corresponding to either a positive road crossing intention or a negative road crossing intention. The remote server device further determines a plurality of proximity values evaluating whether the input image is closer to the positive road crossing intention or the negative road crossing intention, evaluating the image embedding against each of the pretrained embeddings. The remote server device further classifies a road crossing intention of the pedestrian based upon the plurality of proximity values. The system further includes generates a road crossing intention output based upon the road crossing intention of the pedestrian.
