Pattern recognition apparatus

Patent ·
OSTI ID:6456391

This patent describes 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 the image input device and converts the analog signal to a binary signal; a frame memory which receives the binary signal from the converter and stores the binary signal; a template memory for storing templates of different image patterns; a pattern matching circuit which compares the signal stored in the frame memory with the template patterns in the template memory; a template matching circuit which compares the template patterns in the template memory with each other and selects similar template pattern pairs; and a featured template forming circuit which automatically forms mismatched portions of the template pattern pairs as a feature template and registers the featured template.
