My proposed solution to the focus problem exploits the abundance of digital image sensor resolution to sample each individual ray of light that contributes to the final image. ... To record the light field inside the camera, digital light field photography uses a microlens array in front of the photosensor. Each microlens covers a small array of photosensor pixels. The microlens separates the light that strikes it into a tiny image on this array, forming a miniature picture of the incident lighting. This samples the light field inside the camera in a single photographic exposure. ... To process final photographs from the recorded light field, digital light field photography uses ray-tracing techniques. The idea is to imagine a camera conigured as desired, and trace the recorded light rays through its optics to its imaging plane. Summing the light rays in this imaginary image produces the desired photograph. This ray-tracing framework provides a general mechanism for handling the undesired non-convergence of rays that is central to the focus problem. What is required is imagining a camera in which the rays converge as desired in order to drive the final image computation.
The Breitbart chief and Trump campaign CEO’s sexist bullying was evident in the early days of Biosphere 2 in Arizona, then a quasi “space colonization” and environmental research project. Stephen K. Bannon, who recently took a leave from running Breitbart.com to become Donald Trump’s chief campaign executive, once bullied women in the historic environmental research […]
Jesse Singal requested this shoop, and I delivered. After all, who’s downloading pirated papers? Everyone. (I’ve uploaded this to Redbubble if you’d like a poster—of course, you can just as well pirate it.)
If you’re like us, packing and unpacking are two of your least favorite aspects of traveling. Specifically with multi-destination trips, our suitcases usually end in wrinkled clothing, toothpaste stains, and a misplaced deodorant.The good news is that we’ve found a suitcase that eliminates the disastrous effects of packing and unpacking: The Rolo Travel Bag ($42.99). You essentially use it […]
Finding quality icons is a challenge for designers, and can also get pretty costly if you use them often. And when you’ve got a lot to do, the last thing you want to spend your time on is creating new icons from scratch That’s why we recommend using the Noun Project ($49). Noun Project is a site […]
