Abstract

In pattern recognition technology, recognition is effected of alphanumeric characters which are printed or handwritten. In general, this is accomplished by scanning the printed character, translating the resulting data into a field which describes the characteristics of the scanned material, and then comparing this field with reference fields which describe the characteristics of possible alphanumeric characters. A match between a scanned field and a particular reference field determines which character is scanned.

Pattern Recognition System

In pattern recognition technology, recognition is effected of alphanumeric characters which are printed or handwritten. In general, this is accomplished by scanning the printed character, translating the resulting data into a field which describes the characteristics of the scanned material, and then comparing this field with reference fields which describe the characteristics of possible alphanumeric characters. A match between a scanned field and a particular reference field determines which character is scanned.

This system stores the reference fields corresponding to the alphanumeric characters of interest in associative memory 2. The scanned data is placed in register 4. By normal associative memory operation, in which the compares are done in parallel, an indication is obtained of which reference field compares to the scanned field.

Memory 2 is an associative-only store AOS because its contents, unlike a conventional associative memory, are never read out or changed. Only a comparison with a field is made and compare or no-compare signals are obtained from the associative-only store.

The same technologies used in a ROS can be used to implement the AOS. An example is given in B. The core acts in a linear mode, i.e., as a transformer core to provide coupling between lines which link it. In the ROS technology, the word line either does or does not link the core and, hence, does or does not couple the word line pulse to the sense line...
