1. A navigation system for a host vehicle, the navigation system comprising:
at least one processor comprising circuitry and having access to a memory, wherein the memory includes instructions that when executed by the circuitry cause the at least one processor to:
receive at least one image acquired by a camera onboard the host vehicle, the at least one image having been acquired from an environment of the host vehicle; and
analyze the at least one image using a trained model, the trained model being configured to:
identify a plurality of candidate regions, each of the plurality of candidate regions corresponding to a representation of an object in the at least one image;
determine a plurality of scores, each of the plurality of scores indicating a degree to which a corresponding one of the plurality of candidate regions corresponds to a representation of a lane marking in the at least one image, the plurality of scores being generated by the trained model;
analyze the plurality of scores to select one of the plurality of candidate regions; and
output an indicator of the selected candidate region.
