Abstract
A method for recognizing and providing an output corresponding to a character is disclosed. The character is received by an imager, digitized and transmitted to a buffer memory. Data in the buffer memory is read in a sequence which circumnavigates the test character. Only data representative of the periphery of the character are read. During the circumnavigation character parameters, such as, height, width, perimeter, area, calipers, programmable penetrators and waveform are determined. The character parameters are compared with reference character parameters and the ASCII code for the reference character which matches the character is provided as an output.
