Learning Spherical Convolution for Fast Features from 360 Imagery
While 360 cameras offer tremendous new possibilities in vision, graphics, and augmented reality, the spherical images they produce make core feature extraction non-trivial. Convolutional neural networks (CNNs) trained on images from perspective cameras yield "flat filters, yet 360 images cannot be projected to a single plane without significant distortion. A naive solution that repeatedly projects the viewing sphere to all tangent planes is accurate, but much too computationally intensive for real problems. We propose to learn a spherical convolutional network that translates a planar CNN to process 360 imagery directly in its equirectangular projection. Our approach learns to reproduce the flat filter outputs on 360 data, sensitive to the varying distortion effects across the viewing sphere. The key benefits are 1) efficient feature extraction for 360 images and video, and 2) the ability to leverage powerful pre-trained networks researchers have carefully honed (together with massive labeled image training sets) for perspective images. We validate our approach compared to several alternative methods in terms of both raw CNN output accuracy as well as applying a state-of-the-art "flat object detector to 360 data. Our method yields the most accurate results while saving orders of magnitude in computation versus the existing exact reprojection solution.
Edinburgh to Dubai flight turned back over Egypt due to airport drone attack
Hundreds of passengers flying to Dubai spent 11 hours on a flight to nowhere after their plane was turned back over Egypt. The Emirates flight EK24 set off from Edinburgh at 21:26 on Sunday and was due to land in Dubai at 06:49 on Monday. However, as the plane flew over Egypt, flights at Dubai International Airport were suspended following a fire caused by an Iranian drone hitting a fuel tank. The plane was forced to return to Edinburgh. Travel journalist Simon Calder told the BBC's Radio Scotland Breakfast programme that although Dubai was on the UK Foreign Office's No go list, many people were still taking the risk of flying there. No injuries were reported following the drone strike but officials said they had taken all necessary measures to ensure public safety.

During WWI, a daredevil pilot helped invent the first 'drones'
During WWI, a daredevil pilot helped invent the first'drones' Lawrence Sperry's autopilot proved planes could fly themselves. Lawrence Sperry was a pioneer, a showman, and inventor. Without him, flying today would look very different. Breakthroughs, discoveries, and DIY tips sent six days a week. On November 21, 1916, pilot and inventor Lawrence Sperry was flying over Long Island's Great South Bay with his student Dorothy Rice Pierce when his plane suddenly plunged into the water .

Blend attack [6]: We first generate a trigger pattern where each pixel value is sampled from auniform distribution in[0,255]asshowninFigure 6(c). Input-aware Attack (IAB) [30]: The dynamic trigger varies across samples as shown in Figure 6(d). We apply two types of target label selection. Clean-labelAttack(CLB)[42]: The trigger is a3 3checkerboard at the four corners of images as shown in Figure 7(b).
