    I am working on a similar project and having the same issues. As a matter of fact, recognition results are very poor. The biggest problems I am having with letters E, D, P, A. Below is the dictionary file that I compiled. In many cases it recognizes E as P, D, C. Letter A recognizes as 8 or H.

    What techniques would you recommend for improving accuracy? Doesn’t more combinations for the same letter help?
