Scientists Can Restore Images from our Brain
Google DeepMind’s artificial intelligence technologies are developed to read human thoughts. However, neurologists at the University of Toronto Scarborough, Canada, have managed to use AI for the purpose of restoring images. They used data collected by electroencephalography (EEG).
Course of Study
During the tests, people were connected to the EEG and showed different faces. At the same time, the researchers recorded their brain activity, and then analyzed the data. The machine learning algorithms were used by them. As a result, the scientists could apply this information in order to digitally recreate the face of a person accumulated in the human memory. Unlike basic forms, the capability to restore images includes a high quality of visual details, demonstrating the complexity of technology.
For the first time, the process has been performed with EEG data. Previously, researches included fMRI technology. Earlier the brain activity was measured by identifying differences in human blood flow. One of the most interesting distinctions between these methods is that the EEG is handy, cheap and can provide a higher level of details in milliseconds.
Perspectives of the system
This technology can be used to create very accurate witness reports by identifying potential suspects. Moreover, this can work for disabled people who do not have the opportunity to communicate verbally. EEG could be used for creation a neural reconstruction of what a person perceives at given time, as well as visualization of memories or imaginations.
