1, Xiaoying
Xiaoying is a professional video production platform with rich material library, which can meet the various needs of users for video. At the same time, Xiaoying also supports many formats, such as mp4, mov, 3gp and so on. , can also be generated with one click. In addition, in the finished video, users can also choose whether to add a watermark.
2. Magic mirror
Mirror is Tencent's short video social platform. Its function is similar to that of Tik Tok, and it can also realize the special effect of AI changing face. However, the magic mirror is more powerful. In addition to AI face-changing special effects, it also has many functions such as matting, beauty and filter.
3、B6 12
B6 12 is an intelligent editing tool based on artificial intelligence technology. It has powerful cutting and synthesizing ability, can easily and automatically splice multiple pictures or short videos, and can quickly generate a beautiful video by simple dragging. The operation is not only very simple, but also very effective.
The principle of ai changing face:
Face exchange can generally be used for video synthesis, providing privacy services, portrait replacement or other innovative applications. At the earliest time, face exchange was realized by analyzing the similar information of two faces respectively, that is, feature point matching was used to extract feature information such as eyebrows and eyes from one face and then match it to another face.
This realization does not need training and data sets, but it is relatively poor and cannot modify the expressions in the face by itself. In the recently developed deep learning technology, we can extract the deep information of the input image through the deep neural network, thus reading the hidden deep features and realizing some novel tasks.
There is also face exchange using neural network, in which VGG network is used to extract features and realize face exchange. Here we realize face exchange through a special self-encoder structure, and achieved good results.
