Effect of the perturbed correlation method for optical character recognition

In order to verify effectiveness of the perturbation method in the optical character recognition procedure, the improvement of performance was experimentally confirmed by applying perturbation to all six parameters of two-dimensional affine transformation. The technique of character recognition consisted of reciprocal directional features, directional features, and correlation, and was applied to the character database, the handwritten Kanji database ETL8b2. As a result of the experiment, the recognition accuracy was improved by 5%, and the maximum correct recognition rate was 97.4%. The problem to be solved is the enormous amount of computation of the procedure requires. There are a large number of parameters to which the perturbation is applicable other than affine transformation, and extension of this approach makes the problem diverge
