Scroll through ever Instagram and see yourself looking a little rough in the background of a friend’s photo? A new AI-engineered camera can fix the problem for you before it happens — even if it’s intended more as a solution for surveillance cameras than your friend’s smartphone. Digital cameras are everywhere, and they can see you a lot ofThanks to facial recognition technology, body movement tracking and medical imaging.
These cameras capture countless details every day, resulting in massive databases and raising serious privacy concerns. To try and refine what some of these lenses see, a team of researchers from the University of California, Los Angeles, has created cameras that teach them to capture important objects while erasing others from the shot.
what’s new – People typically train computers to recognize sensitive content in images (such as license plate numbers or human faces) and hide the information by blurring, encrypting, or using some other masking method. But the raw image shows it all – and this is a security risk. This is especially true if your images reside on a cloud-based server, where it’s easy for hackers to steal personal information.
To preserve our data in a short period of time, UCLA bioengineer Idoğan Özkan and his team have come up with a smart camera that focuses on the importance as they report in a new study. For example, the camera can show a person walking through a security line while simultaneously blurring the faces of uninvolved onlookers.
The camera – The new smart camera has up to seven 3D printed layers. Ozcan’s team used deep learning to map these 3D-printed surfaces into thousands of tiny features that bend light to transmit certain objects and eliminate others from the final assembled image. The tool removes unnecessary visuals by converting them into random noise-like patterns, as shown above.
To demonstrate its effectiveness, the scientists trained the camera on a group of handwritten numbers – 2, 2, 5, and 9 – on terahertz waves. They thought of holding only number 2 and successfully blocked numbers five and nine from the final image. They tested the camera in different lighting conditions and confirmed that it works well in different environments.
The device is mostly intended for surveillance cameras, Ozkan said. vice versa. “But one can imagine their use at home,” he added. “You just want to track your pet or senior for remote monitoring.”
Their invention could pave the way for encrypted cameras that allow people with the decryption key to access the images they want.
Best of all, the new smart camera is energy efficient compared to previous blurring techniques, all of which required computers to process the image.

On the horizon…
Indoor lighting makes us sick. It throws off our circadian rhythms and can predispose people to chronic inflammation, which is linked to other conditions like cardiovascular disease, neurodegeneration, and even cancer. Since Americans spend an average of 90 percent of their time at home, that’s a big problem.
A new study suggests that we can use artificial lights containing quantum dots, nano-sized crystals that can transport electrons, to mimic the daily sunlight exposure that keeps our biological clocks running smoothly.
Unlike standard LEDs that emit white light in three colors — red, green and blue — qunatum-dot-LEDs expand the palette to create a dynamic lighting system that mimics the changing colors of daylight. Quantum dots are already used to power LCD displays and provide accurate color gamut, but they could eventually bring the outdoors into our homes and offices.
The system can’t exactly recreate sunlight—at least, not yet. For a person, artificial lights are difficult to compete with the high light intensity (or lux) outside.
But the research could prove a bright future for those of us stuck at home most of the day.
Gehan Amaranga, a professor of engineering at the University of Cambridge, said in a press release: “This research paves the way for a variety of new human-responsive lighting environments.”
