Abstract
To reduce a decrease in search accuracy in a technique for comparing feature values acquired by collecting a local feature value by patch unit, the present invention provides an image processing apparatus 10 including: an image processing unit 11 that detects an object region occupied by an object in an image; a patch size decision unit 12 that decides a patch size, based on a size of the object region; a patch unit feature value-computation unit 13 that sets a plurality of patches having the patch size described above in the object region, and computes a patch unit feature value acquired by collecting a local feature value in a patch for each patch; and a search unit 14 that searches for an image similar to a query image from among a plurality of reference images by using the patch unit feature value.
