A method is proposed for estimating deformation of printed characters. In this method, displacement, rotation, dilation/erosion, and magnification are taken to be character-deformation parameters, and character deformation is estimated by measuring changes in these deformation parameters with respect to a standard character. To measure the deformation from a standard character, the target character is deformed using a genetic algorithm, the deformed character is matched up with a standard character, and deformation parameters are determined for the best match between two characters. An experiment performed on several characters demonstrated that these deformations as well as missing and excess sections could be measured.
