ABSTRACT:
The character pattern from the scanner is stored in its original form in an auxiliary memory and in compressed form in a main memory. The slant and the horizontal and vertical second-order moments of the character pattern are sensed in the main memory, and normalized as the character pattern is shifted from the auxiliary memory to the main memory.
