Embodiment 1

[0062] as attached figure 1 , attached figure 2 And attached image 3 As shown, the special effect processing method of video face texture, the special effect processing method of video face texture, attaches any image as a texture to any position of the human face in the input video, and the texture maintains the relative position of the specified texture area of ​​the human face in the video fixation, including the following steps:

[0063] (1) Carry out feature location to the face in the video, and obtain the facial feature points of the face;

[0064] (2), import the selected image into the human face in the video as a texture, the texture includes a texture image and a texture control point, calculate the position parameters of the texture control point through the texture control point and the facial feature points of the corresponding face, and pass the texture The position parameter of the control point transforms the texture image, and the position parameter of t...

Embodiment 2

[0176] as attached Figure 4 And attached Figure 5 As shown, this embodiment is a further improvement on the basis of Embodiment 1. The difference between this embodiment and Embodiment 1 is: in step (3), in order to solve the texture of the texture of the human face in the video and the light and shade of the texture and the lighting The influence is consistent to avoid the problem that the texture does not change when the lighting changes (such as yin and yang faces). We use the V component of the HSV color space of the specified texture area of ​​the face in the video to shade the deformed texture image, and superimpose the shaded texture on the specified position of the face in the input video by linear superimposition.

[0177] Through the V component of the HSV color space of the specified texture area of ​​the face in the video, the transformed texture image is shaded, specifically including the following steps:

[0178] 1) Perform color space conversion on the video...

Embodiment 3

[0217] as attached Image 6 As shown, the video facial map special effect generation system of the present invention includes a display module, a function module and a prompt module, and the function module includes a video import editing submodule, a map definition editing submodule and an effect adjustment submodule; the video import editing submodule and the display Module connection, can select video source and import video, can number each frame of video image, and can perform face detection and face feature point positioning on video; texture definition editing sub-module is connected with display module, and can be loaded as a texture image, and can edit and save the position parameters of texture control points; the effect adjustment sub-module is connected with the video import and editing sub-module, texture definition editing sub-module and display module respectively, and can adjust the transparency and brightness of the video and texture, and can choose Display...

Abstract

The present invention discloses a video facial attaching picture effect processing method and generation system and belongs to the video effect field. The invention aims to make a user edit the effectof an attaching picture and adjust the position and size of the attaching picture by himself or herself. The method comprises the following steps that: feature positioning is performed on a face in avideo so as to obtain the facial feature points of the face; a selected image is imported and added on the face in the video so as to be adopted as an attaching picture, wherein the attaching pictureincludes an attaching picture image and attaching picture control points, the position parameters of the attaching picture control points are calculated according to the attaching picture control points and the facial feature points of the face which are corresponding to the attaching picture control points, and transformation processing is performed on the attaching picture through the positionparameters of the attaching picture control points, and the position parameters of the attaching picture control points can identify a relative position relationship between the attaching picture anda specified attaching picture area of the face in the video; and the attaching picture which has been subjected to the transformation processing is added onto the specified attaching picture area of the face in the video. The structure of the system includes a display module, a function module and a prompting module. With the video facial attaching picture effect processing method and generation system adopted, a user can edit the effect, position and size of an attaching picture by himself or herself.

Description

technical field [0001] The invention relates to the field of video special effects, in particular to a method for processing special effects of video face textures and a system for generating them. Background technique [0002] With the expansion and homogenization of information, people hope that personalized features can be reflected in the video, so as to gain recognition faster, while satisfying the inner experience and conveying their own emotions. For example, quickly superimpose texture special effects on the face of the video and keep it at the relative position of the face. Due to the complexity of video processing, if the general video post-processing software is used for processing, the operation is difficult and requires professional knowledge and a large number of manual operations, which is not suitable for ordinary home users. [0003] At present, the existing applications are mainly to add some predefined beauty effects or dynamic special effects to personal...
