【発明の名称】英数字文字画像認識装置
Document Type and Number:
Japanese Patent JP3001790
Kind Code:
B2
Abstract:
An alphanumeric character image recognition system comprising: a first stage (2) comprising at least a first (R1), second (R2) and third (R3) digital image signal processing network having each at least one input terminal and at least one output terminal and said networks (R1,R2,R3) being designed to process image information from digital image signals, and comprising at least a first (REG1), second (REG2) and third (REG3) memory register having each at least one input terminal and at least one output terminal and the input terminals of the first (REG1), second (REG2) and third (REG3) memory registers being connected to the output terminal of the first network (R1), the output terminal of the second network (R2) and the output terminal of the third network (R3) respectively and said memory registers being designed to contain the image information processed by the first R1, second (R2) and third (R3) digital image signal processing networks, and a second stage (3) characterised in that said second stage (3) comprises at least one first (ST1) and one second (ST2) statistical network having each at least one first and one second input terminal and a plurality of output terminals, the first input terminal of the first statistical network (ST1) being connected to the output terminal of the first memory register (REG1) and the second input terminal of said first statistical network (ST1) being connected to the output terminal of the second memory register (REG2) and the first input terminal of the second statistical network (ST2) being connected to the output terminal of the second memory register (REG2) and the second input terminal of said second statistical network (ST2) being connected to the output terminal of the third memory register (REG3) and at least one third statistical network (STOUT) having a plurality of input terminals connected to a plurality of output terminals of the first (ST1) and second (ST2) statistical networks and a plurality of output terminals which are output terminals of the system (1) and said statistical networks being designed to carry out consecutive statistical operations on the image information until there are obtained statistical values corresponding to a predetermined classification of images to be recognised.
