An object recognize apparatus suitable for recognition of a complex object constituted with a plurality of elements. When specifying a recognition object, a plurality of elements constituting the finally required recognition object are respectively designated as recognition objects, and when specifying an upper-level recognition object, lower-level recognition objects thereof are designated. Furthermore, for each lower-level recognition object, geometric features necessary for the recognition are specified. In an analysis of image data, the lower-level recognition objects are first detected by use of the geometric features so as to next attain the upper-level recognition object based on results of the detection. As a result, a complex object existing at an arbitrary position can be judged and the position thereof is obtained.
