  • Eventful Cloud Service
    1 Eventful Cloud Service Ibraheem Alhashim School of Computing Science Simon Fraser University Surrey, BC, Canada [email protected] Abstract We present a crowd-sourced service that enable users to experience large social events with the focus on the context of the captured media. In order to enable such a rich experience, a centralized service needs to organize and annotate a large number of media files including photos, videos, and live streams. Our cloud based service receives user generated content and construct a 3D representation of the physical world. The system uses structure from motion algorithms to estimate camera poses of the contributed media. This information is used in a 3D media viewer that allows users to explore many images and videos in their original context. We demonstrate the potential of such a service with a proof-of-concept implementation applied on a small dataset of media items. I. INTRODUCTION A number of user-generated media sharing web services have emerged in recent years. An early prominent example of these services is the Flickr image and video hosting website [1]. The ability to publicly share user media have also expanded to most social networking sites such as Facebook, Twitter, and Instagram all of which have millions of active users. Most of these services organize their media based on authors, album collections, playlists, or user assigned tags. Other services, such as Google’s Panoramio and 360Cities, focus on geotagged content that relates to physical locations and so organize their media spatially. All of these services allow users to explore past events after the media is collected and organized, thus losing the excitement and appeal associated with live events.

  • Your Business Identity on Google: Be Found, Stand out and Engage
    YOUR BUSINESS IDENTITY ON GOOGLE: BE FOUND, STAND OUT AND ENGAGE January 2015 WHAT IS GOOGLE MY BUSINESS? Google My Business made its much-anticipated debut in June Google My Business combines multiple platforms – Google 2014, replacing Google Places for Business and Google+ pages as Search, Google Maps and YouTube – into a single, user-friendly a turnkey, digital solution for local businesses like car dealerships. interface. Existing content from the dealer’s Google+ page is consistent across all Google products. Building an optimized Google My Business page is a crucial step toward strengthening a dealership’s online brand and boosting its visibility in search. BUSINESS DASHBOARD: STEER YOUR GOOGLE MY BUSINESS PAGE IN THE RIGHT DIRECTION Just as a car’s dashboard shows vital information – speedometer, tachometer, fuel, oil and temperature gauges – the Google My Business digital dashboard provides dealers with real-time analytics and performance data. A dealer can access all of their Google services from this central dashboard, edit their business information, add photos, share updates and manage their online reviews. A dealership’s Google My Business page is considered complete and verified if it contains all the required and relevant business information. 1 THE KNOWLEDGE GRAPH IS KEY TO MAXIMIZING ONLINE PRESENCE The Knowledge Graph is the focal point of the Google My Business interface. Located on the right-hand side of a Google Search Engine Results Page (SERP), this highly visible section prominently displays the dealership’s most relevant information: • Business Name • Physical Address • Phone Number • Hours of Operation • Photos • Google Ratings • Snapshot of Google Reviews In the example below, a branded search – using a dealership’s brand name as part of the search string – for “BMW of Riverside” yielded the following results: • A Pay-Per-Click (PPC) ad containing location extension (i.e., dealership address) is served up at the top of the page, which is considered optimal placement.

  • CAREER: Observing the World Through the Lenses of Social Media
    CAREER: Observing the world through the lenses of social media This is a five-year proposal for an integrated research, education, and outreach program on the algorithms and technologies needed for data mining in large, unstructured collections of photographs from online social media. The billions of photos on these sites, including both their visual content and non-visual metadata like text tags, GPS coordinates, and timestamps, contain an enormous amount of latent information about the state of the world and about human activities. The proposed project is based on the hypothesis that if aggregated together, these billions of observations could create virtual ‘distributed cameras’ or ‘social sensor networks’ that produce fundamentally new sources of observational data about the world, with the potential to impact a wide range of scientific disciplines that require such data including ecology, biology, psychology, and sociology. Unlocking this latent information will require innovative algorithms and technologies in data mining, applied machine learning, and large-scale computer vision. The proposed research plan involves both investigating these core technologies and validating them with ap- plications in ecology and psychology through interdisciplinary collaborations. The PI’s expertise and recent work in modeling social networks, mining social media, recognizing objects and scenes, and reconstructing 3D models from large-scale photo collections lays the foundation for this project. The proposed education plans will develop new curricula for data mining and computer vision at both the undergraduate and graduate levels to help prepare students for the era of ‘big data’ jobs that increasingly rely on machine learning, data mining, probabilistic inference, and statistics.

  • Automatically Augmenting Lifelog Events Using Pervasively Generated Content from Millions of People
    Sensors 2010, 10, 1423 - 1446; doi:10.3390/100301423 OPEN ACCESS sensors ISSN 1424-8220 www.mdpi.com/journal/sensors Article Automatically Augmenting Lifelog Events Using Pervasively Generated Content from Millions of People Aiden R. Doherty ? and Alan F. Smeaton Centre for Sensor Web Technologies, Dublin City University, Glasnevin, Dublin 9, Ireland; E-Mail: [email protected] Received: 24 December 2009; in revised form: 19 January 2010 / Accepted: 3 February 2010 / Published: 26 February Abstract: In sensor research we take advantage of additional contextual sensor information to disambiguate potentially erroneous sensor readings or to make better informed decisions on a single sensor’s output. This use of additional information reinforces, validates, semantically enriches, and augments sensed data. Lifelog data is challenging to augment, as it tracks one’s life with many images including the places they go, making it non-trivial to find associated sources of information. We investigate realising the goal of pervasive user-generated content based on sensors, by augmenting passive visual lifelogs with “Web 2.0” content collected by millions of other individuals. Keywords: lifelogging; event augmentation; SenseCam; Web 2.0 1. Introduction Almost everything we do these days is in some way monitored, sensed, or logged. We’ve come to accept—or maybe we just ignore—this massive surveillance of our lives from a variety of sensors because it brings us benefits. For example, we have a more secure feeling when we know there is CCTV present, we get itemised billing of our phone usage from phone companies, and we get convenience and even loyalty bonuses as a result of some of our regular store purchases.

  • Towards Seamless Multi-View Scene Analysis from Satellite to Street-Level
    PROCEEDINGS OF THE IEEE, DOI: 10.1109/JPROC.2017.2684300 1 Towards seamless multi-view scene analysis from satellite to street-level Sebastien´ Lefevre,` Devis Tuia, Senior Member, IEEE, Jan D. Wegner, Timothee´ Produit, Ahmed Samy Nassar Abstract In this paper, we discuss and review how combined multi-view imagery from satellite to street- level can benefit scene analysis. Numerous works exist that merge information from remote sensing and images acquired from the ground for tasks like land cover mapping, object detection, or scene understanding. What makes the combination of overhead and street-level images challenging, is the strongly varying viewpoint, different scale, illumination, sensor modality and time of acquisition. Direct (dense) matching of images on a per-pixel basis is thus often impossible, and one has to resort to alternative strategies that will be discussed in this paper. We review recent works that attempt to combine images taken from the ground and overhead views for purposes like scene registration, reconstruction, or classification. Three methods that represent the wide range of potential methods and applications (change detection, image orientation, and tree cataloging) are described in detail. We show that cross-fertilization between remote sensing, computer vision and machine learning is very valuable to make the best of geographic data available from Earth Observation sensors and ground imagery. Despite its challenges, we believe that integrating these complementary data sources will lead to major breakthroughs in Big GeoData. arXiv:1705.08101v1 [cs.CV] 23 May 2017 This is the pre-acceptance version, to read the final, published version, please go to the DOI: 10.1109/JPROC.2017.2684300.

They still hold the promise of a new world, but sometimes this new world looks as much like a complex form of neofeudalism as a celebration of a new communality. In such a situation the question of what ‘media’ or ‘communications’ are has become strange to us. It demands new ways of thinking about fundamental conceptions and ecologies of practice. This calls for something that traditional media disciplines, even ‘new media’ disciplines, cannot always provide. The Fibreculture book series explores this contemporary state of things and asks what comes next.
