Embodiment Construction

[0043] The present invention utilizes the distance between the feature points on the face image and the ratio information of the reference facial features to adjust the plane reference face model to approximate the corresponding face model, eliminating the step of establishing the corresponding face model, And use the position of the feature points to correctly attach the face image to the adjusted model.

[0044] Before explaining the method of the present invention, some related information is first defined, first as Figure 2a As shown, it is a standard reference face image 20, and according to this reference face image 20, a Figure 2b The plane reference human face model 22 shown; In addition, in order to adjust the plane reference human face model 22, then must provide as image 3 The standard reference facial features ratio of the human face 20 is shown, and then a preset cross line 24 is established according to the reference facial features ratio of the reference hum...

Abstract

The invention is a method of rapidly building a human-face video plane model, avoiding building a corresponding human-face model to the human-face video, only requiring the user to provide a little special information, thus able to directly regulate a plane reference human-face model to approximate the corresponding human-face model, and then pasting the human-face video on the regulated plane reference human-face model, where the plane reference human-face model is a plane model defined in advance. Therefore, as soon as the user gives a little special information, the human-face video can be pasted on the plane reference human-face model approximate to the corresponding human-face model.

Description

technical field [0001] The present invention relates to a method for rapidly establishing a plane model of a human face image, in particular to a method for quickly establishing a plane model of the same or similar human face image by using a plane reference human face model and a small number of facial feature points. Background technique [0002] Click to attach the face image to a face model, and then adjust the control points on the model to achieve changes in facial features. It is a very mature technology, and its application level is very wide, for example: Changes in facial expressions, changes in the shape of the mouth when speaking...etc. [0003] In order to achieve the change of the face, the known technology usually requires the user to provide a one-to-one correspondence between the feature point and the control point between the face image and a face model, and then there is a way to attach the image to the model, such as Figure 1a As shown, the user first pr...
