A set of computer subroutines which attempt to simulate various degrees of distortion and deterioration on an input character is developed. A complete set of the letters of the Cyrillic alphabet, numerals, and some punctuation were quantized and punched to be used as ideal input characters to transforming subroutines. These transforming subroutines permit the generation of large sample sets of characters containing controlled amounts of various types of distortion. Use of the routines will produce a set of test characters in which the pattern size, percentage distortion or amount of shift, and number of output samples desired are parameters. The out put of any of the programs developed can be used as the input to a character recognition routine. It is the object of this study to produce a variety of source pattern representations of the same pattern. The use of these programs is demonstrated in conjunction with a recognition routine.
