1. A system for digitizing input information from a first information type to a digital format, comprising:

  • a memory that stores computer readable code; and

    a processor operatively coupled to said memory, said processor configured to;

    analyze said input information to determine if at least one of at least first and second characteristics is present, wherein said processor is further configured to;

    recognize said input information with a plurality of prioritized recognition methods that exhibit varying degrees of improved recognition for a certain characteristic of the input information; and

    determine whether a general recognizer or an intermediate recognizer produces a script closer to a reference output;

    select output information recognized with a first recognition method if said analyzing step determines that said input information includes said first characteristic; and

    select output information recognized with a second recognition method if said analyzing step determines that said input information includes said second characteristic.
