Besides Athena Chu, Barbara Yung, Zhou Xun, and Ariel Lin, there is also Yang Mi who played Huang Rong in The Legend of the Condor Heroes?

Don’t believe it, look at the picture:

Why does this look like the Huang Rong played by Athena Chu in the 1994 version of The Legend of the Condor Heroes? Even the painting style feels like the 1990s.

It turns out that a B station UP host named "Face Changing Brother" used AI technology to "paste" Yang Mi's face onto the face of Huang Rong, played by Athena Chu.

Look, this is a screenshot of the original version:

We replaced Zhu Yin's face with Yang Mi:

Look at Zhu Yin's expression:

The same goes for Yang Mi:

After the face transplant, the facial contours and expressions are the same, and it is impossible to tell that they are artificial.

The whole video is also very smooth.

Such an effect immediately attracted a group of onlookers, and the reading volume of the topic on Weibo reached 110 million.

So, what is the story behind AI face-changing?

Not only Zhu Yin has become Yang Mi

Since the deepfake face-changing program was introduced to China, many netizens have made face-changing videos, such as replacing the female anchors that otakus love with popular Chinese actresses.

Some replaced the anchor A Leng with Tang Yan:

Some replaced Feng Timo with Zhao Liying:

The above ones are considered to have good results, with hundreds of thousands of views.

Most videos are limited by the materials and hardware, and the production levels are uneven. For example, the problems of mismatched face shapes and unnatural expressions are still very serious. In short, they just don’t look like the real thing.

Netizens lamented: Even if the face is changed to Dilraba Dilmurat, it looks like Huang Zitao's evil smile.

AI face-changing technology deepfake has been around for more than a year, creating countless fake videos. Abroad, it has been led to an "unspeakable" direction.

It has caused a sensation on the Reddit forum, and even a dedicated discussion area has emerged.

Various "unspeakable" videos on a well-known website "Pernhaps" were replaced with the faces of Hollywood actresses. Scarlett Johansson, the goddess in the hearts of many men, and Gal Gadot, Wonder Woman, were both affected.

Face Swap Tutorial

I don’t dare to have bold ideas, but you may want to make a face-changing video that suits your own hobbies according to the domestic usage suitable for all ages.

The threshold is not high, and you don’t even need to train a deepfake model yourself, there are ready-made programs to use.

In January 2018, someone launched the Windows program FakeApp , which allows users to easily make their own face-changing videos, even without any knowledge of AI, greatly lowering the threshold for using deepfakes.

FakeApp only needs a personal computer with an Nvidia GPU and 3-4GB of storage space to generate face-changing videos. As for the materials for training neural networks, users need to find them by themselves.

With the software, related text and video tutorials came into being.

First, you need to download the FakeApp software. It is recommended to have a Nvidia 1060 or higher graphics card and install CUDA toolkit 9.0.

Next, face swapping is divided into three steps: obtaining the original data set, training the model, and converting the video.

According to the program requirements, there are videos of the two people whose faces are replaced and the two whose faces are replaced, and their videos are converted into 256×256 images.

Then adjust the appropriate number of nodes, number of layers, and Batch Size. Different graphics memory has different recommended parameters.

When the training result is less than 0.02, the training program can be stopped. This process requires a long wait, which may last 8 to 12 hours.

Finally, select the trained video and face-changing video above, and set the appropriate frame rate to get a homemade deepfake video.

Warm reminder : Due to the extreme controversy of FakeApp, its official website has been shut down. Please do not use the face-changing tutorial for illegal purposes.

Netizen: Will there be a bad guy who will change my face?

The face-changing effect is so high that it is indistinguishable from the real thing, which has caused concern among some netizens.

Some people are worried that criminals will use AI face-changing technology to do bad things, such as fraud:

Others feel that if the technology is used on ordinary women, such as in some indescribable videos, it will harm the legal rights of many women:

In addition, many foreign female celebrities including Scarlett Johansson and Emma Watson have also suffered from this problem. They were inexplicably replaced in pornographic films. Websites such as Twitter and PornHub also prohibit uploading such face-changing content.

The video in the account of "Face Changing Brother" who uploaded the face-changing video has also disappeared, leaving only two pictures. The video is currently no longer available on Bilibili.

However, in the face of controversy, the UP host himself believes that new technologies should be made known to everyone, giving the public a "vaccination" so that when they see similar fake videos in the future, they will realize that "this is generated by AI" and will not be deceived by fake news.

AI face-changing is a new technology, and people don't know enough about it. I hope more friends will know about it. Otherwise, when someone forges a video with negative content about a celebrity in the future, it will cause greater losses to public figures. These works do not have any malicious intent and are not for commercial purposes. If you think these contents are detrimental to your rights, please contact me privately and I will deal with it in a timely manner (｀・ω・´)

It is precisely because photo processing software such as PhotoShop has become popular today that people can realize that strange pictures are fake when they see them, and will not believe them and be deceived. PS software itself has created a large number of interesting pictures, emoticons, jokes and other content for us.

In addition, the AI ​​community is also using various methods to identify such face-swapped videos. New AI models are used to automatically search the entire Internet for similar videos to determine whether they are fake face-swapped videos. The academic community is also building databases to help train AI to identify deepfake videos.

In the future, as long as everyone has enough knowledge and realizes that videos are "Photoshopped", then as long as they abide by the law and respect the portrait rights of others, it is not wrong to use face-changing technology for entertainment purposes like Photoshopping to create emoticons, and it can also create more interesting content for us.
