17. The system of claim 15 , wherein the one or more programming instructions that, when executed, cause the computing device to determine a posterior probability associated with each of one or more possible characters comprise one or more programming instructions that, when executed, cause the computing device to: determine a probability of evidence value; determine a prior probability value; determine a prior probability of evidence value; and determine a product of the probability of evidence value and prior probability value.
17. The system of claim 15 , wherein the one or more programming instructions that, when executed, cause the computing device to determine a posterior probability associated with each of one or more possible characters comprise one or more programming instructions that, when executed, cause the computing device to: determine a probability of evidence value; determine a prior probability value; determine a prior probability of evidence value; and determine a product of the probability of evidence value and prior probability value. 18. The system of claim 17 , wherein the computer-readable storage medium further comprises one or more programming instructions that, when executed, cause the computing device to: construct an input/output table comprising one or more probabilities, wherein each probability is associated with a true value and one or more character recognition proposed values, wherein the one or more programming instructions that, when executed, cause the computing device to determine a probability of evidence value comprise one or more programming instructions that, when executed, cause the computing device to identify the probability from the input/output table that corresponds to the proposed value and the possible character.
