Using functional magnetic resonance imaging (fMRI), researchers have created artificial intelligence capable of converting brain waves into quality videos.
- An artificial intelligence would be able to translate brain waves into video.
- For this, artificial intelligence uses functional magnetic resonance imaging (fMRI).
- This is a first because, until now, scientists had only managed to recreate static images.
Create a video from brain waves? This is the project “MinD-Video” that researchers have just developed. Their work, still being validated, has been pre-published on the platform Arxiv.
Artificial intelligence creates videos from the brain
MinD-Video is an artificial intelligence capable of creating high-quality videos from harvested brain waves via data fromimagery by functional magnetic resonance (fMRI), a technique that uses a very small unit of measurement.
The goal of this project is to recreate human vision in video based on the activities of the brain. Until MinD-Video, scientists had succeeded in recreating static images from brain recordings, but never from videos.
To develop their artificial intelligence, the scientists taught him how to process fMRIs and convert them into videos. This operates by “layers” of images: the first transcribe the information structural and deeper ones tweak with more abstract visual features.
Artificial intelligence is improving
“Our analysis highlights the role of the visual cortex in processing visual spatiotemporal information”, explain the researchers. The visual cortex is an area of the brain that processes everything related to sight. Recently, researchers have also shown that, in people born blind, this part of the brain is used for other cognitive functions unrelated to vision, such as understanding speech or memory.
Scientists note that as it learns, artificial intelligence places less and less strain on the visual cortex and focuses more on higher cognitive networks. This means that the artificial intelligence improves, during its training, its ability to assimilate more detailed information… To give a better video result.
Eventually, the researchers hope that their artificial intelligence will improve knowledge of the brain and cognitive process.
