Abstract: 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.

Abstract: Systems and methods are described for acquiring and decoding a plurality of images. First images are acquired and then processed to attempt to decode a symbol. Contributions of the first images to the decoding attempt are identified. An updated acquisition-settings order is determined based at least partly upon the contributions of the first images to the decoding attempt. Second images are acquired or processed based at least partly upon the updated acquisition-settings order.
