1. A method comprising: accessing a plurality of images depicting a reference object in disassembled states, wherein the reference object in a disassembled state requires the assembly of one or more additional parts to be in the assembled state; determining that the reference object is depicted in particular images of the plurality of images in particular states of disassembly based on changes in the depiction of the reference object between two or more images; processing an image of a first object to identify characteristics of the first object, the first object being in a disassembled state in the image; comparing the image of the first object in the disassembled state to images of the reference object in disassemble states; and identifying one or more additional parts required for the first object in the disassembled state to be in an assembled state based on the comparison of the image of the first object in the disassembled state to images of the reference object in disassemble states.
