A pattern extraction apparatus, comprising: inverse image generation means (1) for generating an inverse image obtained by changing a label of an input image; recognition means (2) for performing a pattern recognizing process on a pattern extracted from the input image and a pattern extracted from the inverse image; and output means (3) for outputting a nonoverlapping combination of an area of a pattern extracted from the input image and an area of a pattern extracted from the inverse image generated by said inverse image generation means, from among the recognition results from the recognition means. The apparatus may be applied, for example, to recognising headlines in newspapers. <IMAGE> |
