Abstract
Described herein are systems and methods for performing optical character recognition in documents such as, in certain embodiments, a printed receipt from the sale of an item. In certain embodiments, the systems utilize a time dimension associated with inputs—for example, the expectation that the system will identify components in future related inputs—in order to increase speed and accuracy. The processing time and computing resources required diminish for each subsequent processing stage, and the embodiments described herein have the ability to self-train, attempting computationally more complicated algorithms in the case of a non-match or ambiguous result at previous stage.
