Abstract: PURPOSE:To accelerate a character recognition processing by extracting strokes of a character pattern, then by extracting intersections and branch points of the character in accordance with the extracted connection relation and by connecting appropriately spaces between strokes comprising character intersections. CONSTITUTION:An unknown character 2 on a document 1 is read out by a character reader 3, its noises are removed in a pretreatment circuit 5 through an A/D convertor 4, and said character is stored in a picture memory. After a feature extraction circuit 6 encodes features (intersection, branch point, loop, etc.) of the character, it extracts them, while a dictionary collation circuit 7 collates them with a feature code of a standard pattern stored in a dictionary 8. When both of them are coincident, said circuit 7 outputs a discrimination label of the standard pattern having the feature code. If a candidate character cannot be specified by the feature code outputted by the feature extraction circuit 6, the dictionary collation circuit 7 trakes strokes comprising the candidate character, and collates the tracked result with a preset standard tracking pattern. When they are coincident, the discrimination label of the standard pattern having the standard tracking pattern is outputted.
