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 replacement method and system based on local affine and color transfer technology, which solves the defect that real-time human face replacement cannot be achieved compared with the prior art. The present invention comprises the following steps: video acquisition, acquiring the target face video through a camera, and intercepting the current frame image; detecting the face and its feature points; performing face transformation; performing face fusion processing; checking whether the camera is closed, if closed , then end the face replacement; if it is not closed, continue video capture and obtain the current frame image, and continue the steps of face detection, face transformation and face fusion. The invention improves the quality, speed and efficiency of face replacement, and can be used for real-time replacement in 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...
