There are colors all around us that we cannot see – but a new pair of glasses could soon change that. While human color vision relies on three types of photoreceptor cone cells, the specs essentially trick the eyes into having a fourth, allowing a person to see distinct hues that would otherwise appear identical. The design opens the door to a slew of new'meta-colors,' revealing a much wider array of blues, violets, and purples, and the researchers say it could one day be taken even further to double our number of effective cone types. Typical human color vision is trichromatic, using three types of cone cells to process blue, green, and red wavelengths. But, other animals are equipped with more complex visual systems that can process additional wavelengths.
Computer vision is a branch of AI that focuses on extracting useful information from pictures and videos. If AI allows computers to think, computer vision allows them to watch, learn and comprehend. Computer vision is architected in a similar way to human vision. Humans learn by seeing things repeatedly and identifying patterns. Our brains are comprised of an incredibly large network of interconnected neurons that mysteriously store and process information.
Bats often navigate rapidly through complex environments by using echolocation, a sensory modality that is profoundly different from human vision (1). Building a sufficient three-dimensional perception of their environment on a lower-dimensional sensory input than human vision, they perform a complex task. They are thus forced to apply a high degree of processing and interpretation to the sensory input, making them prone to sensory deceptions.
Though no price was announced, the Daydream headsets will be more expensive than Cardboard, likely in the ballpark of Samsung's 100 Gear VR. By contrast, Google sells Cardboard for as little as 15, and many brands, including The New York Times, give them away as part of promotions. The price difference gives you better materials -- not cardboard -- and a strap to keep your hands free.
A sensor that mimics the way a human eye responds to light could make digital cameras more efficient. This could pave the way to faster, more efficient machine vision for things like self-driving cars and robots. Some modern cameras are built around charge-coupled devices (CCDs), which produce a voltage when light falls on them. Continuous light produces a continuous signal. By contrast, retinal cells produce a spike only when first lit up, reacting further only when the light changes.
