    • An image retrieval method includes reading from a first database a first image group mapped to an object as a retrieval target, and extracting an image feature quantity of a plurality of images of the first image group. A second image group mapped to an object as a search key is read from a second database and an image feature quantity of a plurality of images of the second image group is extracted. Similarity is determined between the first image group and the second image group, based on the image feature quantity of the plurality of images of the first image group and the image feature quantity of the plurality of images of the second image group. On an output device, as retrieval results, the plurality of images of the first image group are displayed in order of similarity of the object as the retrieval target based on determined similarity.
    • 图像检索方法包括从第一数据库读取映射到作为检索对象的对象的第一图像组,以及提取第一图像组的多个图像的图像特征量。 从第二数据库读取映射到对象作为搜索关键字的第二图像组,并且提取第二图像组的多个图像的图像特征量。 基于第一图像组的多个图像的图像特征量和第二图像组的多个图像的图像特征量,在第一图像组和第二图像组之间确定相似度。 在输出装置上,作为检索结果,基于确定的相似度,以对象作为检索对象的相似度的顺序显示第一图像组的多个图像。
