Problems solved by technology

[0005] However, with regard to the migration technology of facial expressions, the domestic ones are not mature enough. At present, this technology can mainly be reflected in some special effect apps. From the experience point of view, there are mainly the following shortcomings: (1) The expressions are not rich enough, only It can show about 4 kinds of expressions, such as anger, anger, surprise and other exp

Embodiment Construction

[0058] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0059] Such as figure 1 As shown, the first aspect of the present invention relates to a migration method S100 of human facial expressions, including:

[0060] Step S110, acquiring the color image of the current frame.

[0061] Specifically, in this step, for example, a color camera may be used to acquire the current frame color image of the user.

[0062] Step S120, perform face detection on the current frame color image, and execute step S130 when a human face is detected, otherwise, execute step S110.

[0063] Specifically, in this step, face detection may be performed on the current frame color image by using a face detector or other devices capable of de...

Abstract

The invention discloses a method and a device for transferring facial expressions. The method comprises acquiring a current frame color image and detecting a face thereof, calculating positions of a plurality of preset key points of the face of the current frame color image; calculating a projection matrix according to the positions of a plurality of preset key points of a human face of a currentframe color image and the positions of a plurality of preset key points of a preset deformation model, using the projection matrix, the neutral expression and expression base corresponding to the preset key points of the deformation model being projected into the two-dimensional space to obtain the projection results.; according to the projection results and the positions of some preset key pointsof the face in the color image of the current frame, a set of linear equations being constructed, and the weight coefficients of expression bases being calculated, so that the real-time expression ofthe face can be obtained; according to the real-time facial expression driven cartoon model, the facial expression migration is completed. vivid transfer of people's various expressions can be realized in any posture.
