Abstract: A device captures an image of a first item and generates a first encoded vector for the image. The device identifies a set of items that have at least one attribute in common with the first item. The device determines the identity of the first item based at least on attributes of the first item. The device determines that a confidence score associated with the identity of the first item is less than a threshold percentage. In response, the device determines a height of the first item. The device identifies item(s) with average heights within a threshold range from the height of the first item. The device compares the first encoded vector with a second encoded vector associated with a second item from the identified item(s). If the first encoded vector corresponds to the second encoded vector, the device determines that the first item corresponds to the second item.

Abstract: A device detects a triggering event that corresponds to a placement of a first item on a platform. In response, the device captures an image of the first item and generates a first encoded vector for the image. The first encoded vector describes one or more attributes of the first item. The device determines a height of the first item. The device identifies one or more items in an encoded vector library that are associated with average heights within a threshold range from the determined height of the first item. The device compares the first encoded vector with a second encoded vector associated with a second item from among the one or more items. The device determines that the first encoded vector corresponds to the second encoded vector. In response, the device determines that the first item corresponds to the second item.
