Abstract
An information processing apparatus includes a detecting unit, an extracting unit, a managing unit, and a deriving unit. The detecting unit detects an object from an image. The extracting unit extracts a feature amount of the object detected by the detecting unit. The managing unit manages an element in the object detected by the detecting unit in association with the feature amount of the object in the element. The deriving unit derives a reliability indicative of a certainty for identifying an object with respect to the feature amount of the element.
Claims22
An information processing apparatus comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the information processing apparatus to function as:
- a detecting unit configured to detect an object from an image,
- an extracting unit configured to extract a feature amount of the detected object,
- a deriving unit configured to derive a reliability for an extracted feature amount, wherein the derived reliability is indicative of a certainty for identifying an object with respect to the extracted feature amount,
- a managing unit configured to manage an element in the detected object in association with the extracted feature amount and the derived reliability, and
- an identifying unit configured to identify a selected object among a plurality of images,
- wherein, in a case where the information processing apparatus receives input to identify a selected object based on a search condition that includes a selected feature amount associated with an element, the identifying unit identifies the selected object among the plurality of images based on the search condition, feature amounts associated with elements managed by the managing unit, and derived reliabilities.
A method for an information processing apparatus, the method comprising:
- detecting an object from an image;
- extracting a feature amount of the detected object;
- deriving a reliability for an extracted feature amount, wherein the derived reliability is indicative of a certainty for identifying an object with respect to the extracted feature amount;
- managing an element in the detected object in association with the extracted feature amount and the derived reliability;
- and
- identifying a selected object among a plurality of images;
- wherein, in a case where the information processing apparatus receives input to identify a selected object based on a search condition that includes a selected feature amount associated with an element, identifying includes identifying the selected object among the plurality of images based on the search condition, managed feature amounts associated with elements, and derived reliabilities.
A non-transitory computer readable recording medium storing a program to cause an information processing apparatus to perform a method, the method comprising:
- detecting an object from an image;
- extracting a feature amount of the detected object;
- deriving a reliability for an extracted feature amount, wherein the derived reliability is indicative of a certainty for identifying an object with respect to the extracted feature amount;
- managing an element in the detected object in association with the extracted feature amount and the derived reliability;
- and
- identifying a selected object among a plurality of images;
- wherein, in a case where the information processing apparatus receives input to identify a selected object based on a search condition that includes a selected feature amount associated with an element, identifying includes identifying the selected object among the plurality of images based on the search condition, managed feature amounts associated with elements, and derived reliabilities.
