Problems solved by technology

[0009] On the other hand, in the template matching of an image area divided into parts, although it is possible to perform matching by absorbing shading, etc., the amount of calculation required for block matching is very large, which is problematic in practical use.

Embodiment Construction

[0018] In order to further specifically illustrate the present invention, it will be described according to the accompanying drawings.

[0019] figure 1 It is a schematic block diagram of a face image matching system using the face metadata generation device of the present invention.

[0020] Refer to the following figure 1 , to describe the facial image matching system in detail.

[0021] Such as figure 1 As shown, the face image matching system based on the present invention has: a face image input device 11 for inputting a face image; Metadata generating means 12; face metadata storage means 13 for storing the face metadata generated (extracted) by the face metadata generating means 12; face similarity for calculating the degree of similarity of faces based on the above face metadata Degree calculating device 14; Store the facial image database 15 of above-mentioned facial image;

[0022] According to image registration requirements and retrieval requirements, the cont...

Abstract

A face meta-data creating technique in which the description length is short and which is used to extract the face feature for face recognition immune to the local error. An area cut-out section ( 121 ) cuts out a local area of a face image. Frequency feature extracting means ( 122 ) extracts the frequency spectrum of the local area. Vector projection means ( 123 ) projects the obtained frequency feature onto a partial space to extract the face feature of the local area. Aface meta-data unit ( 12 ) extracts the face features from local areas cut out in different positions, thus creating face features as face meta-data.

Description

technical field [0001] The present invention relates to a face recognition technology that can be used for face identification, face recognition, facial expression recognition, male and female recognition through faces, age judgment through faces, etc., and particularly relates to a method for generating still images A metadata generating device, a generating method, and a generating program for metadata related to facial information in moving images. Background technique [0002] Metadata generally refers to data that describes the meaning of data or data that represents the meaning of data. When performing face recognition, metadata mainly refers to data related to face data such as still face images and moving images. [0003] The activities of MPEG-7 (Moving Pictures Experts Group-7) are widely known among metadata standardization activities related to multimedia contents such as images, images, and audio. Among them, for the descriptor as metadata related to face reco...
