Embodiment Construction

[0091] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0092] Such as figure 1 As shown, the video real-time face replacement method based on local affine and color transfer technology of the present invention comprises the following steps:

[0093] The first step is video acquisition, read the video under the current camera, obtain the target face video through the camera, and intercept the current frame image to prepare for post-processing.

[0094] The second step is to detect the face and its feature points. For the obtained target face image, use a strong classifier to detect the face, train the samples in the face database based on the shape model that has been built, and combine the target face feature points with the samples in the face database The feature points are matched, t...

Abstract

The invention relates to a video real-time human face substitution method and a video real-time human face substitution system based on a partial affine and color transfer technology, which solve the defect that the real-time human face substitution cannot be achieved when compared with the prior art. The video real-time human face substitution method comprises the steps of: carrying out video acquisition to obtain target human face video through a camera, and intercepting a current frame image; detecting a human face and feature points thereof; carrying out human face substitution; carrying out human face fusion processing; checking whether the camera is turned off; finishing the human face substitution if the camera is turned off; and continuing the video acquisition and acquiring the current frame image if the camera is not turned off, and continuing the human face detection, human face substitution and human face fusion steps. The video real-time human face substitution method and the video real-time human face substitution system improve quality, speed and efficiency of human face substitution, and can be applied to real-time substitution in the video.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a video real-time face replacement method and system based on local affine and color transfer technologies. Background technique [0002] Face replacement technology is an important research direction in the field of computer vision. Because face replacement technology replaces various drawbacks such as photoshop and other software for manual image editing and fusion, it has a huge impact on business, entertainment and some special industries. . For example, some dangerous action movies that require stunt actors to perform are all shot first by stunt doubles, and then in post-production, the face of the stunt actor is replaced with the required face of the character by using automatic face replacement technology to achieve the ultimate goal of the film . At this stage, many researchers have proposed different replacement strategies and achieved some success, but they c...
