Filed: 1986-05-29
Abstract: PURPOSE:To facilitate the classification of image data by providing a 1st means that obtains and distinguishes the patterns of splited small areas and a 2nd means that automatically extracts the features of the image data on a category name and classifies said data with the aid of the features. CONSTITUTION:When plural names of categories cannot be sorted out at some level of a classification tree in order to classify the patterns of the image data, the image data is divided into plural areas. The 1st means which obtains and distinguishes the patterns of the splited small areas (learning) and the 2nd means, which investigates all the patterns that a specific category name at some level has, extracts the feature patterns, repeats the classification with the aid of the extracted feature patterns by dropping the level, and improves until one node and one category can be obtained, classifies image data. Thus a classification tree can be generated without giving no structural feature of a binary image picture, which has been found manually, regardless of the type and size of an input picture.
