ABSTRACT:
In order to perform pictorial pattern recognition at an extremely high data rate, a linear array of photodetectors reads information recorded on photograhic film and the data read is transferred sequentially to an array of microprocessors, converted into binary form and stored in the memories. The microprocessors operating in conjunction with transformation logic then perform successive transformations using an analysis technique, known in the art, which utilizes hexagonal surrounds.
