A method for recognizing and providing an output corresponding to a character in which the character is received by an imager, digitized, and transmitted to a memory. Data in the 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 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.
