Problems solved by technology

[0003] Since the changes in the eyes and mouth are more obvious when the face makes an expression, the current face image synthesis method generally only considers the synthesis of the eyes and mouth.

[0036] continue to refer figure 2 , shows a flow 200 of an embodiment of the image synthesis method according to the present disclosure. The image synthesis method includes the following steps:

[0037] Step 201, based on the selected initial human face image, determine the average pixel value of each area in the eye image, mouth image and initial human face image.

[0038] In this embodiment, the execution body of the image synthesis method (such as figure 1 The shown server 104) may select a face image as an initial face image from a large number of face images pre-stored locally or in a communication-connected database server. Wherein, the face image may be an image showing a human face.

[0039] In this embodiment, after the initial face image is selected, the execution subject may further determine the eye image and the mouth image. Wherein, the eye image may be an image showing human eye parts determined from the initial human face image, and the mouth image may be ...

Abstract

The embodiment of the invention discloses an image synthesis method and device. A specific embodiment of the method comprises the steps of determining average pixel values of all areas in an eye image, a mouth image and an initial face image based on a selected initial face image; generating a human face three-dimensional model of the initial human face image based on the obtained expression coefficient, the posture parameter and a reference three-dimensional model of the initial human face image; and inputting the eye image, the mouth image, the average pixel value of each region in the initial face image and the normalized coordinates of the three-dimensional pixel points in the face three-dimensional model of the initial face image into a pre-trained image synthesis model to obtain a synthesized face image. According to the embodiment, discordance among eyes, mouths and other parts in the synthesized face image is avoided.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to an image synthesis method and device. Background technique [0002] With the development of image synthesis technology, in some application scenarios, it is necessary to synthesize face images of the faces indicated by the face images under various expressions and postures. [0003] Since the changes in the eyes and mouth are more obvious when the human face makes an expression, the currently used face image synthesis method generally only considers the synthesis of the eyes and mouth. Contents of the invention [0004] Embodiments of the present disclosure propose an image synthesis method and device. [0005] In a first aspect, an embodiment of the present disclosure provides an image synthesis method, the method includes: based on the selected initial human face image, determining the average pixel value of each area in the eye image, the mo...
