1. A method comprising:
analyzing a first set of multiple frames of image data to determine a first trajectory of a first item across the first set of multiple frames;
determining a first item identifier associated with the first item;
adding the first item identifier to a virtual cart based at least in part on the first trajectory;
analyzing a second set of multiple frames of image data to determine a second trajectory of a second item across the second set of multiple frames;
determining a second item identifier associated with the second item; and
storing an indication that an action associated with the second item identifier is unknown based at least in part on the second trajectory.
