Pattern recognition apparatus
First Claim
Patent Images
1. A pattern recognition apparatus comprising:
- an image input device which inputs an image pattern to be recognized and produces an analog image signal;
an analog-digital converter which receives the analog image signal from said image input device and converts the analog signal to a binary signal;
a frame memory which receives the binary signal from said converter and stores said binary signal;
a template memory for storing templates of different image patterns;
a pattern matching circuit which compares the signal stored in said frame memory with the template patterns in said template memory;
a template matching circuit which compares the template patterns in said template memory with each other and selects similar template pattern pairs; and
a featured template forming circuit which automatically forms mismatched portions of said template pattern pairs as a featured template and registers the featured template.

Abstract
A pattern recognition apparatus includes an image input device for inputting an object pattern, an analog-digital converter for converting an analog image signal from the image input device to a binary signal, a frame memory for storing the binary signal, a pattern matching circuit which compares the signal stored in the frame memory with a template memory, a template matching circuit which compares character and image patterns in the template memory, and a featured template forming circuit which automatically forms mismatched portions of the character and image patterns as a featured template and registers the same therein.
