no. 1 approach

[0045] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. Here, a case where a temporal change is added to an image of a person's face (face image) will be described.

[0046] figure 1 It is a block diagram showing a configuration example of the characteristic change image generation device of the present invention. Such as figure 1 As shown, the characteristic change image generation device includes: an image storage unit 101 which is a database, a comparison unit 102 for comparing images, and a synthesis unit 103 for synthesizing images. The image storage unit 101 is realized by, for example, a magnetic disk drive. The comparison unit 102 and the synthesis unit 103 are realized, for example, by an arithmetic processing unit of a computer and a program executed by the arithmetic processing unit. In addition, in the present embodiment, a storage unit that stores information on a plurality of images corresponds to the ...

no. 2 approach

[0065] Next, a second embodiment of the present invention will be described with reference to the drawings. Figure 4 It is a block diagram showing a configuration example of the characteristic change image generation device of the second embodiment. like Figure 4 As shown, the feature change image generation device includes: an image component accumulation unit 101b, a component analysis unit 102b for performing image component analysis, and a synthesis unit 103 for synthesizing images. The image component storage unit 101b is realized by, for example, a magnetic disk drive. The component analysis unit 102b and the synthesis unit 103 are realized, for example, by an arithmetic processing unit of a computer and a program executed by the arithmetic processing unit.

[0066] In addition, in the present embodiment, a storage unit that stores information on a plurality of images corresponds to the image component storage unit 101b. Also, an image specifying section that specif...

no. 3 approach

[0088] Next, a third embodiment of the present invention will be described with reference to the drawings. Figure 8 It is a block diagram showing a configuration example of a characteristic change image generation device according to the third embodiment. like Figure 8 As shown, the feature change image generation device includes: a yearly change image storage unit 101c, a comparison unit 102 for comparing images, and a synthesis unit 103 for synthesizing images. The temporal change image storage unit 101c is realized by, for example, a magnetic disk drive.

[0089] In addition, in the present embodiment, a storage unit that stores information on a plurality of images corresponds to the temporal change image accumulation unit 101c. And, the matching unit 102 and the synthesizing unit 103 perform a comparison with the first

[0090] The same actions are implemented.

[0091] The age-change image accumulation unit 101c is a database that accumulates face images whose chara...

Abstract

A technique for applying a feature of a side attribute to an original image while keeping a principal feature. An image accumulating unit stores images classified into categories per the age or sex. A merging unit selects a category in accordance with an input category. A matching unit matches the input image and each of images included in the selected category with each other, and selects the image having highest degree of similarity. The merging unit merges the input image and the selected image by carrying out the weighted average and so on, and generates and outputs a merged image.

Description

technical field [0001] The present invention relates to a technique for generating a new image by changing some features of an image and adding other features. In particular, the present invention relates to a feature change image generation method, a feature change image generation device, and a feature change image generation program for generating a new face image by adding features that change over time to a face image of a person. Background technique [0002] In some cases, by assigning a certain feature to an image, a new image to which another feature is added while having the original feature may be generated. As a representative case, consider a face image of the same person at the time of age change in which the characteristics of the age are lost due to aging and the characteristics of the age are revealed. A face image of the same person after age changes is generated by performing a process of reducing the features of the youth and adding the features of the a...
