How to turn a photo into someone else's face?

The new camera can shoot video and change face.

Choose a positive photo, and then choose a favorite video, which can be from your own album, or you can directly use the online video material in the app, and wait for synthesis after selecting it. The only drawback is that only Android is supported at present.

This time the special effects are all from this APP. It has dozens of built-in special effects to choose from, but all of them need to be paid to use. If you just want to have a good time and leave, you can also download it and just play the trial function.

Face changing principle:

Face detection and recognition. Firstly, let the machine identify the face feature value through video positioning including David, and restore David's face to the front, parallel uniform illumination and standard brightness scene through deep learning. Next, do the same for the video containing Jack, and restore Jack to the front, parallel uniform illumination and standard brightness scene.

Determine the transformation matrix: Next, we locate and detect the face information of the original video, and extract features. Then, by comparing the characteristics of Jack and David, the transformation matrix of distortion and illumination is found.

Face replacement: transform Jack based on matrix, that is, restore Jack to the shooting angle and light source scene of the original video to form new face information, and use Jack's logo to enter David.
