Colleges Help Students Fix Their Online Indiscretions

Businesses

A growing number of colleges are providing graduating students tools to improve their online image. The services arrange for positive results on search engine inquiries by pushing your party pictures, and other snapshots of your lapsed judgement off the first page. Syracuse, Rochester and Johns Hopkins are among the schools that are offering such services free of charge. From the article: “Samantha Grossman wasn’t always thrilled with the impression that emerged when people Googled her name. ‘It wasn’t anything too horrible,’ she said. ‘I just have a common name. There would be pictures, college partying pictures, that weren’t of me, things I wouldn’t want associated with me.’ So before she graduated from Syracuse University last spring, the school provided her with a tool that allowed her to put her best Web foot forward. Now when people Google her, they go straight to a positive image — professional photo, cum laude degree and credentials — that she credits with helping her land a digital advertising job in New York.”

Google’s Image Search Now Requires Explicit Queries For Explicit Results

December 12th, 2012 12:07 admin View Comments

Google

Several readers sent word of a change to Google’s implementation of SafeSearch for image searches. There used to be three settings: Off, Moderate, and Strict. (You can still see these settings on, for example, Google’s UK image search.) Now, for U.S. users they’ve made Moderate the default, and the only other option is to “Filter Explicit Results.” Going into settings provides no way to turn it off. That said, Google still lets users search for explicit content if the search terms they enter are specific to that type of content. A Google rep said, “We are not censoring any adult content, and want to show users exactly what they are looking for — but we aim not to show sexually-explicit results unless a user is specifically searching for them. We use algorithms to select the most relevant results for a given query. If you’re looking for adult content, you can find it without having to change the default setting — you just may need to be more explicit in your query if your search terms are potentially ambiguous. The image search settings now work the same way as in Web search.”

Vector Vengeance: British Claim They Can Kill the Pixel Within Five Years

Graphics

MrSeb writes “The humble pixel — the 2D picture element that has formed the foundation of just about every kind of digital media for the last 50 years — may soon meet its maker. Believe it or not, if a team of British are to be believed, the pixel, within five short years, will be replaced with vectors. If you know about computer graphics, or if you’ve ever edited or drawn an image on your computer, you know that there are two primary ways of storing image data: As a bitmap, or as vectors. A bitmap is quite simply a giant grid of pixels, with the arrangement and color of the pixels dictating what the image looks like. Vectors are an entirely different beast: In vector graphics, the image is described as a series of mathematical equations. To draw a bitmap shape you just color in a block of pixels; with vector graphics, you would describe the shape in terms of height, width, radius, and so on. At the moment, bitmaps are used almost exclusively in the realm of digital media — but that isn’t to say they don’t have their flaws. As display (and camera and cinema) resolution increases, so does the number of pixels. The obvious problem with this is that larger bitmaps are computationally more expensive to process, resulting in a slower (or more expensive) workflow. Pixel bitmaps don’t scale very gracefully; reduction is okay, but enlargement is a no-no. There is always the issue of a master format, too: With pixel bitmaps, conversions from one format to another, or changing frame rates, is messy, lossy business. Which finally leads us back to the innovation at hand: Philip Willis and John Patterson of the University of Bath in England have devised a video codec that replaces pixel bitmaps with vectors (PDF).”

Mars

astroengine writes “Using its robotic arm-mounted MAHLI camera, NASA’s Mars rover Curiosity has snapped, quite possibly, the most iconic image to come from the mission so far. By stitching together 55 high-resolution photos, the rover has snapped an ‘arm’s length’ self portrait, capturing its location in the geologically interesting area known as ‘Rocknest,’ including its recent scoop marks in the Martian soil and the base of Mt. Sharp.” Note to NASA: Please sell this image in the form of a fundraising poster.

Science

kkleiner writes “What if you could compress a video clip into a single image? That’s what Jay Mark Johnson, an artist and visual effects director, has accomplished through the use of a special camera technique. He calls the images ‘photographic timelines,’ and his collected works offer quite a shift to conventional perception. Slices of photos are strung together in progression to make a single composite image of a sliver of space spread over an extended period of time.”

Kinect 2 Sensor Output Image Leaks

Input Devices

New submitter rabok writes “If a Microsoft job posting can be believed, we are set to get a new Xbox on store shelves by March 2014 at the latest. Regardless of when it does eventually arrive, it seems an image claiming to be the output of a Kinect 2 has hit the web by a user on twitter. Kinect 2 is expected to be much more accurate — even able to see individual fingers, read lips, and gauge moods. This image seems to back up that improvement in both depth perception and the ability to distinguish individual fingers.”

Debian

sfcrazy writes “The Raspberry Pi foundation has announced the release of the first SD card image based on the Raspbian distribution. The image will make it easier for Raspberry Pi users to switch from ‘generic’ Debian Squeeze to this ‘optimized’ image. The new image is based on Wheezy and optimized for ARM with floating point instructions, and supersedes the Squeeze based soft float image. Benchmarks show much improvement in performance, and the updated software in Wheezy generally improves the usability of the Raspberry Pi.

UCLA Develops World’s Fastest Camera To Hunt Down Cancer In Real Time

Medicine

MrSeb writes “Engineers at UCLA, led by Bahram Jalali and Dino Di Carlo, have developed a camera that can take 36.7 million frames per second, with a shutter speed of 27 picoseconds. By far the fastest and most sensitive camera in the world — it is some 100 times faster than existing optical microscopes, and it has a false-positive rate of just one in a million — it is hoped, among other applications, that the device will massively improve our ability to diagnose early-stage and pre-metastatic cancer. This camera can photograph single cells as they flow through a microfluidic system at four meters per second (9 mph — about 100,000 particles per second), with comparable image quality to a still CCD camera (with a max shooting speed of around 60 fps). Existing optical microscopes use CMOS sensors, but they’re not fast enough to image more than 1,000 particles per second. With training, the brains of the operation — an FPGA image processor — can automatically analyze 100,000 particles per second and detect rare particles (such as cancer cells) 75% of the time.”

How People Communicate on Instagram

June 22nd, 2012 06:00 admin View Comments

The comments and likes of an Instagram photograph become part of the viewer’s experience of that image. On this visual social network, communication is subtle, playful, innocent and devoid of any social expectations. It’s a place where image makers can go to freely express themselves and find other like-minded aesthetes. The adage says that a picture is worth a thousand words, but on Instagram that same photo is worth far more than that. 

The culture of Instagram images is far different from Facebook, which is focused around comments and likes from friends who are in the social circle. 

While many people post their Instagram photos to Facebook and Twitter, the majority of discussions occurs on Instagram, limiting the interaction to those who have smartphones,” says Michaelanne Dye, PR and social media officer at Georgia Tech College of Computing. 

Facebook offers personal information about users (birthday, gender, hometown, current town, relationship status and more), while Instagram includes little more than a user’s name, profile pic, how many photos they have posted and number of followers. The decreased level of social pressure in this space actually makes it easier to start a conversation.

“Unlike Facebook, image sharing on Instagram is not about connecting with long lost friends or making plans for the weekend,” says Dye. “The experience revolves around the quality and creativeness of the image. That, combined with the fact that not everyone is on Instagram (unlike Facebook), provides the feeling of a more closed community in which you have a little bit more anonymity.” 

Instagram does not allow for private messaging between users either. Depending on the Instagram user’s settings, every comment or like is either visible to the public or completely private. Users can choose to watch from the sidelines too, if they prefer. Unlike other mobile photo-sharing apps, it’s impossible to share Instagram images with a select group of friends or followers.  

Instagram is a fascinating way to get to know what types of images other visual thinkers are drawn to. 

“In short, Instagram has created a strong social networking site that focuses strictly on the art of photo sharing and visual engagement,” says Dye. “It’s really about taking a photo and allowing it to become an object of value to other individuals.”
