OBJECT IMAGE DETECTION DEVICE, FACE IMAGE DETECTION PROGRAM, AND FACE IMAGE DETECTION METHOD

摘要

An object image detecting apparatus for determining whether or not an object image exists in a detection target image in which whether the object image is contained is not known includes: an image reading unit for reading a predetermined region of the detection target image as a detection target region; a feature vector producing unit for dividing an image included in the detection target region resized to a predetermined size into a plurality of blocks, calculating a representative value of an image feature amount indicating a predetermined image feature for each of the divided blocks, and producing a feature vector showing a characteristic of the image feature within the detection target region by referring to the representative value; and at least two classifying units for determining whether or not the obj ect image exists in the detection target region by different references based on the image feature indicated by the feature vector.
