Described are computer-based methods and apparatuses, including computer program products, for wafer identification fault recovery. A digital image is received that includes a data symbol comprising a message encoded in a set of data cells. The digital image is processed to form a set of classified data cells, wherein one or more classified data cells from the set of classified data cells comprises an error. User interface data is transmitted comprising the digital image and interactive graphics, the interactive graphics including at least one data cell control. Interaction data is received from the interactive graphics that modifies a data cell location, a data cell state, or both, of at least one classified data cell from the set of classified data cells to form a modified set of classified data cells. An error free decoded message string is generated based on the modified set of classified data cells. |

1. A system for decoding a data symbol marked on an object, the system comprising a wafer identification fault server configured to:
receive a digital image, the digital image comprising an image of a data symbol marked on an object, the data symbol comprising a message encoded in a set of data cells arranged in a regular pattern, each data cell comprising one bit of information encoded using a recognizable mark at a location of the data cell; process the digital image to form a set of classified data cells, wherein one or more classified data cells from the set of classified data cells comprises an error, each classified data cell being associated with a data cell from the set of data cells, and comprising:
a data cell location of the associated data cell in the digital image; anda data cell state indicating a presence of a recognizable mark of the associated data cell in the digital image; transmit user interface data comprising the digital image and interactive graphics, the interactive graphics including at least one data cell control, each data cell control being associated with a classified data cell in the set of classified data cells; receive interaction data from the interactive graphics that modifies a data cell location, a data cell state, or both, of at least one classified data cell from the set of classified data cells to form a modified set of classified data cells; and generate an error free decoded message string based on the modified set of classified data cells. |
