In this paper, we present an adaptive nonparametric solution to the image parsing task, namely, annotating each image pixel with its corresponding category label. For a given test image, first, a locality-aware retrieval set is extracted from the training data based on superpixel matching similarities, which are augmented with feature extraction for better differentiation of local superpixels. Then, the category of each superpixel is initialized by the majority vote of the k -nearest-neighbor superpixels in the retrieval set. Instead of fixing k as in traditional nonparametric approaches, here, we propose a novel adaptive nonparametric approach that determines the sample-specific k for each test image. In particular, k is adaptively set to be the number of the fewest nearest superpixels that the images in the retrieval set can use to get the best category prediction. Finally, the initial superpixel labels are further refined by contextual smoothing. Extensive experiments on challenging data sets demonstrate the superiority of the new solution over other state-of-the-art nonparametric solutions. © 2014 IEEE.

Human action recognition is valuable for numerous practical applications, e.g., gaming, video surveillance, and video search. In this paper we hypothesize that the classification of actions can be boosted by designing a smart feature pooling strategy under the prevalently used bag-of-words-based representation. Founded on automatic video saliency analysis, we propose the spatial-temporal attention-aware pooling scheme for feature pooling. First, the video saliencies are predicted using the video saliency model, and the localized spatial-temporal features are pooled at different saliency levels and video-saliency-guided channels are formed. Saliency-aware matching kernels are thus derived as the similarity measurement of these channels. Intuitively, the proposed kernels calculate the similarities of the video foreground (salient areas) or background (nonsalient areas) at different levels. Finally, the kernels are fed into popular support vector machines for action classification. Extensive experiments on three popular data sets for action classification validate the effectiveness of our proposed method, which outperforms the state-of-the-art methods, namely 95.3% on UCF Sports (better by 4.0%), 87.9% on YouTube data set (better by 2.5%), and achieves comparable results on Hollywood2 dataset. © 1991-2012 IEEE.

Pharma buyout Pharmaceutical company Shire of Dublin is buying rival firm Baxalta of Bannockburn, Illinois, in a US$32-billion deal, after a months-long pursuit. Both companies focus on rare-disease areas, including haematology, immunology and neuroscience. The firms say that as one company they will be able to make $500 million in cost savings. Shire will pay Baxalta shareholders in cash and shares, giving them around 34% ownership of the merged company. The deal is awaiting approval by regulators. Cancer screening The California sequencing-technology firm Illumina announced the formation of a new company, GRAIL, on 10 January. GRAIL will use Illumina’s genetic-sequencing technology to screen for cancer from a blood sample. A ‘liquid biopsy’ would find minuscule amounts of tumour-specific DNA or RNA in the blood before the person felt symptoms of the disease, when it may be easier to treat. GRAIL has more than US$100 million in funding, in part from Bill Gates and from Amazon founder Jeff Bezos. Early star remnants A faraway gas cloud has been discovered that contains tiny amounts of elements heavier than hydrogen and helium — such as carbon, oxygen and iron — that are possible remnants of the Universe’s first stars. The elements were detected in spectra collected by the European Southern Observatory’s Very Large Telescope in Chile, and computer simulations show how the Universe’s first stars would have exploded and spewed the elements out (pictured). The results were reported at a meeting of the American Astronomical Society in Kissimmee, Florida, on 8 January. The cloud is so distant that it appears as it did 1.8 billion years after the Big Bang. China science prize A team led by quantum physicist Jian-Wei Pan was awarded the first-class prize of China’s 2015 National Natural Science Award, one of the country’s top science accolades, on 8 January. Pan and his team at the University of Science and Technology of China in Hefei won for their pioneering work in quantum entanglement and teleportation. For the first time in 11 years, no one was awarded China’s top science prize, the State Supreme Science and Technology Award. Pharmacologist Youyou Tu, who last year won China its first science Nobel, had been tipped for the award. Singapore surge Science spending in Singapore is set to surge by 18%, the government announced on 8 January. At its annual meeting, the country’s Research, Innovation and Enterprise Council endorsed plans to invest 19 billion Singapore dollars (US$13.2 billion) between 2016 and 2020, up from 16.1 billion Singapore dollars between 2011 and 2015. The country will prioritize research funding in four areas: advanced manufacturing, health and biomedical sciences, services and the digital economy, and urban sustainability. Oil-pipeline fight Pipeline firm TransCanada Corporation said on 6 January that it will seek more than US$15 billion in compensation for economic losses under the North American Free Trade Agreement after the Keystone XL pipeline that it was due to build was cancelled (unused pipes pictured). The pipeline would have carried relatively dirty oil from tar sands in Alberta, Canada, to US refineries. But in November 2015, the US Department of State said that the project was not in the “national interest”. TransCanada, which is headquartered in Calgary, called the decision “arbitrary and unjustified”, arguing that the project was environmentally benign. The company is also challenging the decision in the US federal court. H-bomb claims North Korea’s fourth nuclear test on 6 January was almost certainly not a hydrogen bomb, contrary to the country’s claims. The seismic event caused by the test was estimated at magnitude 4.85 by the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization in Vienna. The explosion that caused that event was probably hundreds or thousands of times smaller than would have resulted from a hydrogen bomb, analysts say. North Korea might have tested a boosted fission device: a conventional fission bomb with a small quantity of the hydrogen isotopes tritium and deuterium added. See go.nature.com/gyqqya and page 127 for more. Science passport Seven science publishers, including PLOS and the American Geophysical Union, announced on 7 January that they will start requiring researchers to identify themselves using the ORCID (Open Researcher and Contributor ID) system when submitting papers. Globally, 1.8 million researchers have registered for ORCID’s unique identifiers — machine-readable numbers akin to a scientific passport. The system is run by a non-profit organization that aims to create a transparent record linking scientists to their research outputs (see Nature 526, 281–283; 2015). Chimps returned A legal battle over the ‘personhood’ of two chimpanzees has ended with their return to a primate facility in Louisiana, Science reported on 8 January. The two chimps were loaned to the State University of New York at Stony Brook for use as research animals. Animal-rights group the Nonhuman Rights Project sued in New York to have the animals released to a sanctuary, arguing that the chimps should have certain legal rights afforded to humans. The return of the chimps to the New Iberia Research Center in early December effectively removes the animals from New York’s jurisdiction. Insecticide threat The US Environmental Protection Agency (EPA) said on 6 January that the controversial insecticide imidacloprid does present a threat to bees and other pollinators. The preliminary risk assessment is the first of four on the neonicotinoids, an insecticide class that has been linked to bee declines. The European Food Safety Authority announced on 11 January that it would be updating its own risk assessments of three neonicotinoids — clothianidin, thiamethoxam and imidacloprid. The European Union heavily restricted use of neonicotinoids in 2013 on the basis of previous evaluations. UK drinking guides Any level of alcohol intake increases cancer risk, according to draft guidelines released by the UK Chief Medical Officers on 8 January. Men and women should drink no more than 14 units of alcohol per week — around 7 glasses of wine or 6 pints of average-strength beer — according to the recommendations, which substantially lower the amount for men. The models used to calculate the recommendations considered risks and benefits, for instance cancer and alleged beneficial cardiovascular effects. The guidelines have had a mixed reception, with some complaints that they are ‘nannying’. See page 127 for more. Linear collider Japan should ramp up its expertise as it prepares to host the world’s next-generation particle smasher in the 2020s, reports the country’s High Energy Accelerator Research Organization (KEK) in Tsukuba. An action plan published on 6 January lays out the KEK’s goals for the preparation phases of the International Linear Collider, including a goal to triple the number of home-grown accelerator scientists and engineers. In 2012, Japanese researchers proposed hosting the 31-kilometre-long accelerator, which will smash electrons together with their antimatter partners. However, no government has yet promised any funding. Nations burned off around 143 billion cubic metres of natural gas — roughly 3.5% of global production — into the atmosphere in 2012, according to researchers at the US National Oceanic and Atmospheric Administration (C. D. Elvidge et al. Energies 9, 14; 2016). Data from a polar-orbiting satellite showed that Russia led the way in terms of volume. The practice is common in fields that lack pipelines and markets for natural gas and policymakers are looking for ways to avoid the wastage. 3.9 × 1013 The number of bacteria in a typical human, alongside 3 × 1013 human cells.

This innovative new design, led by Planet Ocean & co-developed by NOC, ASV ltd & The University of Southampton, is around three times smaller than current autonomous underwater vehicles (AUVs). At around 50cm long, their tiny size allows them to be used in ways previously not considered. Microsubs are also able to frequently monitor infrastructure, such as pipelines for corrosion or potential leaks in an extremely cost effective manner. The new ecoSUBμ and larger ecoSUBm are economically and environmentally more cost efficient than their larger counterparts. Furthermore, a 'shoal' of microsubs can work together to collectively create a far superior 3-D map of the underwater environment than a lone AUV. They can survey a large area very quickly, covering hundreds of kilometres. Paired with complementary technologies, such as autonomous surface vehicles and satellites, a more complete picture of the oceanic environment can be constructed than ever before. This new sub was developed at the new Marine Robotics Innovation Centre with the NOC, who have twenty years' experience of AUV development, and Planet Ocean. Kevin Forshaw, NOC's Associate Director, Innovation and Enterprise said "this is an example of a highly innovate new product, that is being rapidly brought to market due to the comprehensive support being offered from the technical team within the Marine Robotics Innovation Centre. Product development such as this, that draws on leading thinking from NOC and the University of Southampton, will help UK PLC to make further inroads into this rapidly expanding global market." The ecoSUB's were unveiled during the Marine Robotics and Technology showcase, a week of events celebrating the one year anniversary of the marine robotics Innovation Centre. This soft launch comes after just one year into a two year project, with the next phase being all about testing before the product officially comes to market at Ocean Business in April 2017. A spin out company from Planet Ocean, ecoSUB Robotics Ltd. has been formed to concentrate on the development and manufacture of these innovative vehicles. Planet Ocean Managing Director Terry Sloane commented "Having our engineers co-located within the NOC, in the new Innovation Centre, has been key to the success of this project and to the speed at which the project has progressed."

Wheel detachment from plant trailers used on public highways represents a significant health and safety hazard and major financial risk, especially for construction and utility companies that rely on these type of trailers to transport machinery such as miniexcavators or road rollers. This study uncovers the antecedents of plant trailer wheel detachment and suggests pragmatic guidance for mitigating this risk. A case study using elements of action research studies the problem in the field through direct observation and stakeholder interviews. Analysis of resulting qualitative data conceptualizes antecedents on which guidance is formulated. Risks are found to result from a combination of physical failure underpinned by inadequate human interventions and poor risk management. The primary contributions of the study are that it describes entirely novel research on trailer wheel detachment, produces new safety guidance for businesses and practitioners that operate plant trailers, and resultantly contributes to lowering the risks identified. © 2014 American Society of Civil Engineers.

IJCAI International Joint Conference on Artificial Intelligence | Year: 2015
In this paper, we propose using augmented hypotheses which consider objectness, foreground and compactness for salient object detection. Our algorithm consists of four basic steps. First, our method generates the objectness map via objectness hypotheses. Based on the objectness map, we estimate the foreground margin and compute the corresponding foreground map which prefers the foreground objects. From the objectness map and the foreground map, the compactness map is formed to favor the compact objects. We then derive a saliency measure that produces a pixelaccurate saliency map which uniformly covers the objects of interest and consistently separates fore-and background. We finally evaluate the proposed framework on two challenging datasets, MSRA-1000 and iCoSeg. Our extensive experimental results show that our method outperforms state-of-the-art approaches.

Salient object detection has gradually become a popular topic in robotics and computer vision research. This paper presents a real-time system that detects salient object by integrating objectness, foreground and compactness measures. Our algorithm consists of four basic steps. First, our method generates the objectness map via object proposals. Based on the objectness map, we estimate the background margin and compute the corresponding foreground map which prefers the foreground objects. From the objectness map and the foreground map, the compactness map is formed to favor the compact objects. We then integrate those cues to form a pixel-accurate saliency map which covers the salient objects and consistently separates fore- and background. © Copyright 2015, Association for the Advancement of Artificial Intelligence (www.aaai.org).
