ABSTRACT:
An apparatus for searching data by feature patterns comprises a plurality of processors operating independent of one another for recognizing individual feature patterns of plural input pattern data, a large-capacity file accesing unit arranged to use data constituted by arrays of results of recognitions outputted from the processors as addresses, and a large-capacity file for storing data associated with a large number of input patterns, respectively, at locations of the addresses corresponding to the feature patterns of the input pattern data, respectively. An apparatus for searching data on the basis of feature pattern comprises a plurality of processors of which at least one is activated in response to the results of the processings performed by the other processors which operate independent of one another for recognizing individual feature patterns of input pattern data, respectively, devices for outputting the results of the processings performed by the other processors to the one processor, controller for controlling the activation of the one processor on the basis of the outputted results of the processings, and a large-capacity file arranged to use data constituted by arrays of the results of recognitions outputted from the plural processors directly as the addresses.
