Abstract
A method of generating a three-dimensional (3D) face model includes extracting feature points of a face from input images comprising a first face image and a second face image; deforming a generic 3D face model to a personalized 3D face model based on the feature points; projecting the personalized 3D face model to each of the first face image and the second face image; and refining the personalized 3D face model based on a difference in texture patterns between the first face image to which the personalized 3D face model is projected and the second face image to which the personalized 3D face model is projected.
Claims14
A method of generating a three-dimensional (3D) face model, the method comprising:
- projecting a personalized 3D face model to each of images associated with a user face;
- and
- refining the personalized 3D face model based on the images to which the personalized 3D face model is projected,
- wherein the refining comprises:
- extracting a correspondence point between the images to which the personalized 3D face model is projected;
- and
- refining a shape of the personalized 3D face model such that a similarity between texture patterns of the images to which the personalized 3D face model is projected increases in a peripheral area of the correspondence point.
A non-transitory computer-readable medium storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations including,
- projecting a personalized 3D face model to each of images associated with a user face;
- and
- refining the personalized 3D face model based on the images to which the personalized 3D face model is projected,
- wherein the refining comprises:
- extracting a correspondence point between the images to which the personalized 3D face model is projected, and
- refining a shape of the personalized 3D face model such that a similarity between texture patterns of the images to which the personalized 3D face model is projected increases in a peripheral area of the correspondence point.
An apparatus for generating a three-dimensional (3D) face model, the apparatus comprising:
- a memory storing computer-executable instructions;
- and
- one or more processors configured to execute the computer-executable instructions such that the one or more processors are configured to,
- project a personalized 3D face model to each of images associated with a user face;
- extract a correspondence point between the images to which the personalized 3D face model is projected;
- and
- refine a shape of the personalized 3D face model such that a similarity between texture patterns of the images to which the personalized 3D face model is projected increases in a peripheral area of the correspondence point.
