AI-Generated Images: The Growing Influence on Social Media

Scientists have created a new way to make lifelike 3D avatars. They use video data to make these avatars very real and detailed. This technology is called NPGA, which stands for Neural Parametric Gaussian Avatars. It uses smart head models and 3D rendering.

These avatars start as a point cloud. This cloud is filled with tiny points that have special data attached to them. This helps the avatar look and move like a real person. You can see these avatars show different facial expressions, even very tough ones. The researchers used high-quality video to train the avatars.

This process includes various people making many different faces. A special model helps track and build the 3D heads. This model, called Mono N PHM, is good at making sure the faces are accurate. Tests show that the avatars keep the look of the real person, even when doing tough expressions.

But, there can be some mistakes. For some extreme faces, the avatars might not look perfect. Still, this technology shows big promise for making realistic 3D avatars.

In another area, AI-generated images are causing problems online. Wired magazine talks about how many fake images are made by AI. People often see these images and believe they are real. For example, an image of Donald Trump with Black voters was completely fake.

Many people just look at headlines and images without checking if they are real. This means fake news can spread easily. It is important to remember that not everything we see online is true. AI can make it hard to tell what is real and what is fake.

In summary, while new AI technologies can create amazing things, they also bring challenges. We need to stay aware of what is real and what is not.
