Efficient 3D Object Segmentation from Densely Sampled Light Fields with Applications to 3D Reconstruction
From Kaan Yücer, Alexander Sorkine-Hornung, Oliver Wang, Olga Sorkine-Hornung: Precise object segmentation in image data is a fundamental problem with various applications, including 3D object reconstruction. We present an efficient algorithm to automatically segment a static foreground object from highly cluttered background in light fields. A key insight and contribution of our paper is that a significant increase of the available input data can enable the design of novel, highly efficient approaches. In particular, the central idea of our method is to exploit high spatio-angular sampling on the order of thousands of input frames, e.g. captured as a hand-held video, such that new structures are revealed due to the increased coherence in the data. We first show how purely local gradient information contained in slices of such a dense light field can be combined with information about the camera trajectory to make efficient estimates of the foreground and background. These estimates are then propagated to textureless regions using edge-aware filtering in the epipolar volume. Finally, we enforce global consistency in a gathering step to derive a precise object segmentation both in 2D and 3D space, which captures fine geometric details even in very cluttered scenes. The design of each of these steps is motivated by efficiency and scalability, allowing us to handle large, real-world video datasets on a standard desktop computer... ( paper )
Greg Nichols for ZDNet: The seventh annual National Robotics Week, which kicks off this week, will see more than 250 events take place across all 50 states. It's a pretty cool time to celebrate robots. A new generation of small, relatively inexpensive, and highly collaborative industrial robots brought new levels of automation to light industry last year. Home robots, in the form of vacuums and lawn mowers, continue to do well in sales, and drones--technically flying robots--are everywhere. I'm literally watching one fly over a park near my house as I write. New kinds of bots are also making early strides. Companies like Savioke are bringing robots to hotels and others likeRevolve Robotics and Double are connecting people via affordable embodied telepresence--especially people whose disabilities prevent them from traveling to school or work.

Roy Bishop for The Japan Times: Child care is a hard job, but somebody, or something, has got to do it. Japanese researchers have developed androids to meet that need, which includes happily reading that fairy tale again and again and again. The androids, which were created by a team of education and robotics specialists at a research facility in Abiko, Chiba Prefecture, are part of a larger system called RoHo Care. Short for Robotic Hoikujo (day care center), RoHo is being touted as a high-tech solution to the staffing crisis that forced the Health, Labor and Welfare Ministry to announce emergency measures this week. “I never thought I’d see this day, but we’re now confident that RoHo could blaze a trail for child care worldwide,” said team leader Makoto Hara. At a briefing on Thursday, Hara introduced a “care-droid” prototype named Or-B, the core component of RoHo’s vision for day care assistance, and said it will undergo a trial run this summer before full-scale implementation in 2018.

Patrick Burnson for Logistics Management: “Robots work in many industries but haven’t made an impact on logistics yet because of the complexity of the work – handling a wide array of different things in an infinite number of combinations, close to people and in confined spaces,” says Matthias Heutger, Senior Vice President Strategy for the Group. “Current research shows that 80 percent of logistics facilities today are still manual. Recently, however, technology is just starting to catch up to meet demands for flexible and low-cost robots that could collaboratively work in logistics.” The report highlights that the development of the next generation of robots that can see, move, react to their environment and work at precision tasks alongside people, is on a fast track powered by the explosion in labor-intensive e-commerce and diminishing and ageing workforces.

Short-term, robotic integration will continue to grow as companies continue to establish automation plans, and long-term, robotic automation will be a standard in every facility. This will be a requirement for companies to compete in the global marketplace.
Combining on-vehicle sensor data with high resolution maps adds another safety level to the autonomous driving system. The automotive industry is looking to its partners and suppliers as they develop HD maps.
Michael Grothaus for FastCompany: Amazon hosted a secret robotics conference in Palm Springs, Florida last weekend, reports Bloomberg. The conference, dubbed "MARS," which stands for "Machine-Learning (Home) Automation, Robotics and Space Exploration," was an invite-only event held at the Parker Palm Springs that brought together experts in the fields of robotics, artificial intelligence, space exploration, and home automation. Amazon has not publicly commented on the conference, but reports on social media from attendees leaked its existence. Bloomberg notes that the conference hosted some big names, including film director Ron Howard and Amazon CEO Jeff Bezos. The event was also attended by a number of academics from MIT, the University of California at Berkeley, and ETH Zurich, sources told Bloomberg. Also in attendance were some CEOs and representatives from companies including Rethink Robotics, Toyota Motor Corp., and iRobot. Cont'd...

From OpenROV: OpenROV Trident Features: Depth: Capable of 100m (will ship with a 25m tether - longer tethers will be sold separately) Mass: 2.9 kg Top Speed: 2 m/s Run Time: 3 hours Connectivity The data connection to Trident is a major evolution from the connection setup of the original OpenROV kit. It uses a neutrally buoyant tether to communicate to a towable buoy on the surface (radio waves don't travel well in water) and the buoy connects to the pilot using a long range WiFi signal. Using a wireless towable buoy greatly increases the practical range of the vehicle while doing transects and search patterns since a physical connection between the vehicle and the pilot doesn't need to be maintained. You can connect to the buoy and control Trident using a tablet or laptop from a boat or from the shore... ( preorder $1,199.00 )
Missy Cummings for Wired: Drones are a big business and getting bigger, a reality that comes with both economic opportunities and risks. The UAV market is set to jump from $5.2 billion in 2013 to $11.6 billion in 2023. Opportunities for delivery services, cinematography, and even flying cell towers could introduce thousands of jobs and reinvigorate an ailing aerospace market. At the same time, drone sales to hobbyists have exploded. Registered drone operators in the US now outnumber registered manned aircraft. In tandem with that growth, close calls with commercial aircraft have more than doubled in the past two years. An analysis of FAA reports by Bard College’s Center for the Study of the Drone counts 28 instances in which pilots changed course in order to avoid a collision. Cont'd...
