1. A method of automating an appliance through a sensing device, the method comprising: receiving a visual image; determining that one or more features in the visual image match with one or more features from at least one previously identified household object, where the determination of the matching one or more features is performed by a visually-based automated process; analyzing one or more quality metrics associated with the match between the one or more features of the visual image and the at least one previously identified household object; and automatically determining that the match is potentially unreliable at least partly based on the analysis of the one or more quality metrics.
