Despite the obvious difference between a chihuahua and a doberman, the human brain effortlessly categorizes them both as dogs, a feat that is thus far beyond the abilities of artificial intelligence. Previous research has established that the brain can recognize and categorize objects extremely rapidly, however the way this process occurs is still largely unknown. Researchers now have pioneered a new image modulation technique known as semantic wavelet-induced frequency-tagging (SWIFT) to further test how images are processed.
