Apparatus for feature recognition of symbols

Claim 1

A SYSTEM FOR RECOGNITION OF SYMBOLS OF COMMUNICATION, SAID SYMBOLS CONSISTING OF LINE ELEMENTS, BY DETECTING AS FIRST, SECOND AND THIRD FACTORS, THE INITIATION AND TERMINATION, CONCAVITY AND CONVEXITY, AND THE DIVERSION AND CONVERSION OF SAID LINE ELEMENTS, WHILE DETECTING AS FOURTH, FIFTH AND SIXTH FACTORS, RELATIVE MAGNITUDE OF SAID FIRST THREE FACTORS, INCLINATION OF LINE ELEMENTS AND RELATIVE DISTRIBUTION OF LENGTH, BOLDFACE AND POSITION OF LINE ELEMENTS, COMPARING SAID SIX FACTORS WITH STORED INFORMATION AND IDENTIFYING THE SYMBOLS THEREFROM, SAID SYSTEM COMPRISING IN COMBINATION, SCANNING MEANS FOR SEQUENTIALLY SCANNING A FIELD OF VIEW IN WHICH THE SYMBOLS ARE LOCATED; A FIRST FACTOR DETRMINATION CIRCUIT INCLUDING INCREMENT DETERMINATION MEANS, A SCANNER CONNECTED TO THE INCREMENT DETERMINATION MEANS, LOGIC MEANS RECEIVING INPUTS FROM A MEMORY AND SCANNER DETECTING INITIATION AND TERMINATION, AND, FIRST TOTALIZING MEANS TO OBTAIN THE TOTAL THEREOF; A SECOND FACTOR DETERMINATION CIRCUIT, INCLUDING, DIFFERENTIATING MEANS, AND FIRST COMPARISON MEANS CONNECTED TO THE DIFFERENTIATING MEANS COMPARING THE OUTPUT THEREOF WITH PRESET VALUES TO DETERMINE THE PRESENCE AND ABSENCE OF CONCAVITY AND CONVEXITY AND DISTINGUISHING BETWEEN THEM; A THIRD FACTOR DETERMINATION CIRCUIT INCLUDING PULSE GIVING MEANS CONNECTED TO THE SCANNING MEANS, SECOND TOTALIZING MEANS TOTALIZING DIVERSIONS AND CONVERSIONS, SUBSTRACTING MEANS CONNECTED TO THE PULSE GIVING MEANS AND RECEIVING INPUTS FROM SAID FIRST AND SECOND TOTALIZING MEANS; A FIRST MATRIX MEMORY CONNECTED TO THE LOGIC MEANS, FIRST COMPARISON MEANS AND SUBTRACTING MEANS OF SAID FIRST, SECOND AND THIRD FACTOR DETERMINATION CIRCUITS; A FOURTH FACTOR DETERMINATION CIRCUIT INCLUDING FIRST SWITCHING AND FIRST INTEGRATING MEANS CONNECTED TO SAID SCANNING MEANS, AND SECOND COMPARISON MEANS WITH A PRESET VALUE THEREIN CONNECTED TO SAID FIRST SWITCHING AND FIRST INTEGRATING MEANS;
