We have created a Handwritten Character Recognition system and now want to test the system on English characters (both digits and alphabets). For digits, we have performed our testing on MNIST data set. However for the English alphabets we have not been able to find any openly available (i.e. available for free), standard data set. All we have been able to find is NIST and CEDAR handwritten data sets, available on their respective official sites, but they come at a substantial cost.
Is there any other, openly available standard data set of English alphabets which can be used for testing the Handwritten Character Recognition system.
