Problems solved by technology

However, real face aging is a slow, continuous, and inevitable process that goes through various age groups such as juvenile, youth, middle-aged, and elderly. The changes in each age group have different rules. The existing technology does not Considering this natural law, therefore, the simulation of face aging is not realistic and natural enough.

Embodiment Construction

[0063] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0064] The explanation of the principle of homology continuity is as follows:

[0065] The inventor found that the real face aging process conforms to the "same origin continuity principle", that is, according to the high-dimensional spatial homology continuity principle, the face aging problem is transformed into a series of homology point positioning problems. The source face and the target face can be regarded as homology points in a high-dimensional space. They have similar attributes but are not completely the same. Then there is a gradual and continuous process between them, which makes the source face transform to the target face , In order to realize the simulation of the face aging process.

Abstract

The invention discloses a method and a device for simulating human face aging based on homologous continuity. The shape feature vector is constructed according to the feature points and the metric iscalculated. The metric and the preset metric are matched and calculated to obtain the corresponding matching face images of each age group which are equal to the preset number. A texture enhancement face prototype is acquired corresponding to each age group; the source target age range of the face image is determined; according to the shape feature vectors, age-related and target shape feature vectors corresponding to the face prototype, the first simulated image simulating the aging of the face shape is obtained. According to the texture feature vector constructed by the pixel points corresponding to the face prototype, the second simulated image which simulates the aging of face texture is obtained. The device comprises: an electronic device which is communicated by a processor, a memoryand a bus; and a non-transient computer-readable storage media. The device performs the method described above. The method and the device can truly and naturally simulate the aging of a human face.

Description

Technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for simulating face aging based on homology continuity. Background technique [0002] In recent years, with the rapid development of graphic images and computer technology, the research on simulating the aging of human faces has extremely important application value in theatrical performance, criminal investigation, etc. [0003] At present, the method of simulating face aging is to directly linearly simulate the source face image to the target face image. No matter how large the age span of the person in the source face image and the target face image is, the face of the target age is directly simulated. Image, for example, the prior art directly simulates the face image of a teenager to the face image of the middle-aged or elderly person. However, the real face aging is a slow, continuous, and inevitable process. After adolescence, youth, middle-aged, old...
