Method, medium, and apparatus for person-based photo clustering in digital photo album, and person-based digital photo albuming method, medium, and apparatus

A person-based digital photo clustering apparatus comprising:

• a face area detection unit to detect a face area from photo data;
• a face feature value extraction unit to extract predetermined content-based face feature value information from the detected face area;
• a clustering hint information obtaining unit to obtain predetermined person-based photo clustering hint information;
• and
• a clustering unit to perform person-based clustering by applying the photo clustering hint information to the extracted content-based face feature value information.

A person-based digital photo albuming method, comprising:

• generating photo description information including a photo identifier for identifying at least a photo;
• generating albuming tool description information supporting person-based photo clustering and including at least a parameter for person-based photo clustering;
• performing photo albuming including the person-based clustering by using at least the photo description information and albuming tool description information;
• generating predetermined photo group description information from photo albumed data from the performing of the photo albuming;
• and
• generating predetermined photo album information by using the photo description information and the predetermined photo group description information.

A person-based digital photo albuming apparatus, comprising:

• a photo description information generation unit to generate photo description information including a photo identifier for identifying at least a photo;
• an albuming tool description information generation unit to generate albuming tool description information supporting person-based photo clustering and including at least a parameter for person-based photo clustering;
• an albuming tool to perform photo albuming including the person-based clustering by using at least the photo description information and the albuming tool description information;
• photo group information generation unit to generate predetermined photo group description information based on an output of the albuming tool;
• and
• photo album information generation unit to generate predetermined photo album information by using the photo description information and the predetermined photo group description information.
