1. A method comprising:
collecting an image containing one or more objects-of-interest;
determining that objects-of-interest appearing in the image have been captured from an off-centered point-of-view;
submitting the image to a trained object detector to determine bounding boxes enclosing objects-of-interest in the image;
for each object-of-interest in the image:
identifying corner endpoints of the object-of-interest;
applying homography to reposition the identified endpoints; and
generating a novel view of the object-of-interest based on the repositioned endpoints, the novel view comprising a more frontal view of the object-of-interest; and
submitting the bounding boxes to one or more downstream tasks.
