Image processing apparatus that retrieves similar images, method of controlling the same, and storage medium

摘要

An image processing apparatus capable of reducing time taken to retrieve a specific image including a specific object area from a plurality of images, even when an image is newly added or a face dictionary is updated. A CPU of the apparatus determines whether or not object search information indicating the image is a candidate image as a candidate of the specific image exists in management information. When the object search information does not exist, the CPU refers to an object dictionary in which feature value data of an objects are registered, and compares feature value data of an object detected from a image and the feature value data of the object dictionary to thereby retrieve candidate images. When the object search information exists, the CPU retrieves candidate images based on the object search information.

主权项

1. An image processing apparatus that retrieves a specific image including a specific object area from a plurality of images, comprising:
a storage unit configured to store management information of each of the images; a determination unit configured to determine whether or not object search information exists in the management information; a first processing unit configured to, in a case where said determination unit determines that the object search information does not exist, refer to an object dictionary in which feature items of objects are registered, and compare a feature item of an object detected from an image and the feature items of the object dictionary to thereby retrieve candidate images as candidates of the specific image; and a second processing unit configured to, in a case where said determination unit determines that the object search information exists, retrieve the candidate images based on the object search information.
