FIELD: image processing means.
SUBSTANCE: invention relates to the field of image processing, namely, to the recognition of a category of an image object. Method of recognizing a category of an image object comprises: an image feature extracting step of extracting feature points of all sampling images in N known categories with a feature point extracting method, and establishing “a known category – sampling image – feature point” correspondence, where N is a natural number greater than 1, and each category comprises at least one sampling image; a cluster analyzing step of performing cluster analysis on all of the feature points extracted using a clustering algorithm, and dividing the feature points into N subsets; an object category determining step of determining an object category Cn for each of the subsets; a common feature acquiring step of acquiring common features among the images in each object category Cn with a search algorithm, where Cn is the nth object category, and n is a positive integer no more than N.
EFFECT: technical result is an increase in the speed and accuracy of the recognition of the category of the image object.
