Square Pixel Inventor Tries to Smooth Things Out

As a scientist at the National Bureau of Standards in the 1950s, Kirsch worked with the only programmable computer in the United States. “The only thing that constrained us was what we imagined,” he says. “So there were a lot of things we thought of doing. One of which was, what would happen if computers could see the world the way we see it?”

Kirsch and his colleagues couldn’t possibly know the answer to that question. Their work laid the foundations for satellite imagery, CT scans, virtual reality and Facebook.

Kirsch made that first digital image using an apparatus that transformed his picture into the binary language of computers, a regular grid of zeros and ones. A mere 176 by 176 pixels, that first image was built from roughly one one-thousandth the information in pictures captured with today’s digital cameras. Back then, the computer’s memory capacity limited the image’s size. But today, bits have become so cheap that a person can walk around with thousands of digital baby photos stored on a pocket-sized device that also makes phone calls, browses the Internet and even takes photos.

Yet science is still grappling with the limits set by the square pixel.

Awesome to read about and his new stuff is doing wonders!
