China News Service, February 25 (China News Financial Reporter, Wu Tao) There is a well-known plot in "Hurricane" – the crazy donkey "goes up the mountain".
Unexpectedly, there are similar plots on social platforms in reality. It is rumored that the "yacht maid party" in Jinji Lake, Suzhou is 3,000 yuan each, and the girl in the poster looks like a real person at first glance. The police follow-up response: It is an AI drawing fraud and has been dealt with. This almost became the first fraud in the field of AI drawing.
From last year’s "photo one-click comic" to now AI can directly draw photos, AI drawing has evolved again? The reporter’s investigation found that some AI drawings on the market can really generate realistic images such as portraits, landscapes and still lifes, and some drawings are viewed with the naked eye in appearance, which is almost indistinguishable from real photos.

The reporter tried a variety of AI drawing apps, and some AI drawing apps were quite intelligent. You could draw whatever you want, similar to ChatGPT, AI drawing could recognize text, and the software would draw according to your description, such as red eyes, black hair, what clothes to wear, what hat to wear, and what scene… The more detailed the description, the closer it would be to what you imagined.
These AI drawing styles can be selected, including national style, Xianxia, two-dimensional, ancient style, steampunk, virtual human, etc. You can even choose the "artist" style, including Akira Toriyama, Hayao Miyazaki, etc.
In terms of model selection, these AI drawings include movie realism, character photos, surreal photos, etc. Among them, the character photo and character photo models are closer to real photos. This is the current "AI directly draws photos" uploaded on the Internet.

Interestingly, these AI drawings can even create pictures with similar contours according to your random "doodling", and no art skills are required at all. If you see a favorite AI drawing, you can also "click the same style" to generate a set of pictures.
Be alert to risks, "cheat" and AI coexist
At present, some "photos" drawn by AI are hot on social platforms, and it is difficult to distinguish between true and false. For example, the above-mentioned "Jinji Lake Maid Yacht Party" incident, according to the Yangzi Evening News: The reporter learned from the Suzhou Public Security Bureau Industrial Park Branch that the police have paid attention to the online "Jinji Lake Maid Yacht Party" incident. The staff told the reporter, "The police station has interviewed the news publisher and has finished handling it."

The reporter also noticed in the experience that the current commercialization of AI graphics is serious, and some APPs are forced to watch 30-second advertisements for each image they produce. Others, under the guise of AI graphics, are unable to draw pictures at all, spending all their time watching advertisements or inducing users to download the APP.
On some social platforms, users are constantly sharing beautiful AI drawings. If you want to download these pictures, you may need to watch advertisements or even download advertising apps. The origin of these apps is unknown, and there may be hidden risks. Many of them are online lending apps.
How has it been achieved, and in what fields is it currently being used?
It is understood that most of the current AI graphics are using a GAN (Production Adversarial Network) technology. According to ChatGPT, some researchers have used GANs to generate realistic landscape paintings that are excellent in color and detail, and can even enhance the realism through tiny details that are difficult for the human eye to detect.

However, according to netizens’ feedback and reporters’ experience, AI drawing has shortcomings in the drawing of "hands". Although it can draw delicate faces, the movements of "hands" do not look so natural.
Some drawing apps even added a "hand drawing" function, but this required more points or fees to obtain this service. "The hand drawing function will regenerate an optimized hand picture based on the original structure." The AI drawing app introduced.
According to an article by Wang Pei, a senior engineer at the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, the application field of GAN is a model with "infinite" generation ability. The direct application of GAN is to model, generate data samples that are consistent with the real data distribution, such as images, videos, etc. In addition, GAN has begun to be applied to the research of speech and language processing, computer virus monitoring, chess game programs and other issues.
