Video

A new prototype video camera is fully self-powered and can produce an image each second, indefinitely, of a well-lit indoor scene. Columbia University researchers designed a pixel that can not only measure incident light but also convert the incident light into electric power.

University of Washington electrical engineers have developed a way to automatically track people across moving and still cameras by using an algorithm that trains the networked cameras to learn one another’s differences. The cameras first identify a person in a video frame, then follow that same person...

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, the team was able to recover intelligible speech from the vibrations of a potato-chip bag photographed...

Three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion,...

Carnegie Mellon University has developed a method for tracking the locations of multiple individuals in complex, indoor settings using a network of video cameras. The method was able to automatically follow the movements of 13 people within a nursing home, even though individuals sometimes...

The SPIE Defense Security & Sensing Show in Baltimore, which began on Monday and ends today, provided attendees with an exhibit hall full of new products and technologies. If you weren’t at the show, here’s some of what you missed:

A Queen's University researcher has created a Star Trek-like human-scale 3D videoconferencing pod that allows people in different locations to video conference as if they are standing in front of each other. Two people simply stand in front of their own life-size cylindrical pods and talk to...

A new video compiles 309 images taken by NASA’s Mars Exploration Rover Opportunity, providing an historic record of a three-year trek that totaled about 13 miles across a Martian plain pocked with smaller craters. While Opportunity was traveling from Victoria crater to Endeavour crater, between...
