In the past, when the mobile phone did not come out, people could only go to the photo studio if they wanted to take pictures. Because it was a rare photo, they would put on their best clothes and carefully pick up themselves. Even if the photos were taken in black and white, they were exceptional. Cherish.
Later, with the advent of flip phones, taking pictures became a very common thing. Although the screen was small, it could clearly take pictures of people and scenes, and the pictures were no longer black and white, but turned into color pictures.
Then the smart phone appeared, in addition to the camera function, it also added interesting camera software, which can beautify your photos to a certain extent.
Up to now, all kinds of camera software are emerging in an endless stream, and AI-changing video software has been developed, which can let you be in any scene without any sense of disobedience. The realization of this technology benefits from our artificial intelligence.
Speaking of artificial intelligence, people's first impression is intelligent robots. But in fact, the scope of artificial intelligence is very large. According to the official definition, artificial intelligence refers to: a person who can correctly interpret external data, learn from these data, and use these learning to achieve specific goals and tasks through flexible adaptation and improvement The ability of the system.
This sentence is very convoluted, but if you split it a little, you will know that artificial intelligence is a branch of discipline that analyzes data, uses data, designs algorithms, and builds systems.
AI face-changing technology is also the application of the subject characteristics of artificial intelligence, accurately creating a face-changing mode that meets the characteristics of each person's face, and full of characters through various special effects.
In this technology, the main difficulties are as follows:
1. A large amount of data needs to be collected.
The core of AI artificial intelligence lies in algorithms, so if you want to implement this technology, you must use sufficient data as a reference, analyze a large amount of data, and build models to get face-changing special effects suitable for everyone.
2. Poor controllability.
In addition to the above-mentioned large amount of data analysis, this technology also faces the problem of poor controllability. Characters' face shape, eye size, eyebrow distance, etc. all need to be operated on a small scale, and each person's facial features are different in size, so it is difficult to ensure that the adjustment is suitable for everyone on a small scale.
3. The production quality is unstable.
Due to the quality of the input data and the instability of the generated model itself, the quality of the generated image may be low.
4. The amount of calculation is large and it is difficult to deploy on the mobile terminal.
Because this technology has strong generation capabilities, it may require hundreds of gigabytes of computation, which is not suitable for mobile deployment.
In order to overcome these technical difficulties and realize this technology, it is necessary to
collect unpaired data as required, and train high-parameter models to generate paired data;
Image quality enhancement for paired data;
Use paired data to train a lightweight model on the mobile terminal.
It can be seen that the application of AI artificial intelligence is in all aspects, not limited to intelligent robots, and systems that need to be accumulated through algorithms in daily life. In the world of artificial intelligence, it is far more than that.
