Abstract

The present invention discloses a method for processing a face in an instant video and an electronic device, and belongs to the field of image processing. The method comprises: acquiring a scale of a reference face; and adjusting the face in a current instant video frame according to the scale of the reference face. According to the method for processing the face in the instant video and the electronic device, which are provided by the present invention, by adjusting the face in the current instant video according to the scale of the reference face, the scale of the face in the current instant video is changed, so that the requirement that a user can adjust the scale of the face in the process of instant video is satisfied, the instant video effect of the user is improved, and the user experience is improved; meanwhile, by adjusting the face scale of the user according to the scale of the reference face, satisfaction of the user to face adjustment can be improved, and the instant video can be performed in the face scale, so that the user is more willing to perform a video call, and thus, the conventional problem that the user is unwilling to perform instant video due to the face scale is avoided, and the user experience is improved.

Description

technical field

[0001] The invention relates to the field of image processing, in particular to a face processing method and electronic device in instant video. Background technique

[0002] With the popularity of instant video applications on mobile terminals, more and more users use instant video applications to interact with others. However, due to the limitations of mobile terminal equipment and the user's own face is too fat or proportional Inconsistency and other reasons make users unwilling to make instant video calls, so it is necessary to provide a face processing method in instant video, so as to improve the user's requirements for facial aesthetics in instant video, and improve the user's willingness to make instant video calls Spend.

[0003] In the prior art, the appearance of the human face in the instant video is improved by performing whitening processing on the human face in the instant video or increasing the brightness of the face.

[0004] However, when...

Examples

Embodiment 1

[0092] An embodiment of the present invention provides a method for processing a face in an instant video, refer to figure 1 As shown, the method includes:

[0093] 101. Obtain the proportion of the reference face.

[0094] Specifically, the process includes:

[0095] obtain a reference face; and

[0096] According to the reference face, obtain the proportion of the reference face.

[0097] The ratio of the reference face includes at least one of a length-width ratio, a facial feature ratio, and a ratio between facial features.

[0098] Among other things, the process can include:

[0099] Get the scale of the stored reference face.

[0100] Wherein, obtaining the reference face may include:

[0101] Obtain multiple feature points of the face in the current instant video frame;

[0102] According to multiple feature points, the face in the face picture with the greatest similarity to the face is obtained as the reference face; or

[0103] Obtain the face in the face pi...

Embodiment 2
