1. A method comprising:
determining, using one or more neural networks and based at least on image data representative of an image having a first spatial resolution:
a first output, associated with a second spatial resolution, indicative of one or more locations of a line; and
a second output indicative of a classification associated with the line;
determining, based at least on the first output and the second output, the one or more locations of the line in the image and the classification associated with the line; and
performing one or more operations based at least on the one or more locations and the classification.
