The Boujou special effects software was developed from research carried out at the Department of Engineering Science. It enables sophisticated computer generated imagery (CGI) to be quickly and easily added to `real' film footage, facilitating the visual effects that feature so importantly in films such as Harry Potter and X-Men. The software has become an essential tool used by film-makers, TV advert producers, and video game manufacturers, and for instance played a pivotal role in helping `The Curious Case of Benjamin Button' win the 2009 Oscar for Best Visual Effects. Between 2008 and 2013, sales of Boujou totalled £1.37 million and this software boosted productivity and profitability right across the global digital entertainment industry.
This case study involves the development and implementation of novel algorithms that control the mapping of depth from a scene being imaged by a camera to an image being viewed on a stereoscopic display so as to make viewing more comfortable for the human visual system. The algorithms, developed at Durham University between 2003 and 2005:
Augmented reality supplements real-world experience by placing graphics over a live camera feed in real-time. Smartphones are a popular and suitable device (ubiquity, portability, and sensor features). However embedded industry practices delivered an inferior experience limiting adoption. Maguire's research-informed innovative integration and implementation of visual effects enabled a high-end cinematic experience. This included integration of user's environment, interaction with characters, motion blur, 3D realistic character, facial animation, exponentially increased capacity for customized narrative and new audiences. The outcomes also expanded the aesthetic and genre of the narrative, sharing user experience and thus reaching significant new user demographics.
Research at the University of Cambridge Department of Engineering on computer vision tracking led to the creation of Extra Reality Limited in 2010, which was subsequently acquired by a new company called Zappar Limited in May 2011. Zappar employs 17 staff and had revenue of GBP612k in the financial year 2012/13, an increase of 35% on the previous year.
Over 50 different brands have used Zappar's augmented reality application across more than 300 offerings in over 17 countries to deliver entertainment-based marketing interactions from 2011 to 2013. [text removed for publication] Examples of partners include Disney, Warner Brothers and Marvel. Zappar has changed attitudes in the media sector by showing that "augmented reality is finally ready for prime time" (President, Creative Strategies Inc, Time Online, 2012).
Professor Kautz and his team have developed two photo manipulation and processing methods (Exposure Fusion and local Laplacian filtering) that are used to produce well-exposed photographs with tuneable local contrast. Both are robust and consistent without requiring any per-image parameter tuning. Due to its reliability and effectiveness, Exposure Fusion is now considered the standard method for blending multiple photographs into a single well-exposed photograph, and is used by a large number of commercial and non-commercial products. Local Laplacian filtering was chosen by Adobe Systems Incorporated to be the default tool for image enhancements in Adobe Lightroom and Adobe Camera Raw. As a result, these methods are now in the hands of hundreds of thousands users, who use them to create and manipulate well-exposed digital photographs.
The explosive growth in the number of CCTV cameras has meant that analysing the volume of data produced has become almost unmanageable. Dublin based start-up Kinesense Ltd was incorporated in 2009 by Dr Mark Sugrue, who had carried out his PhD in Video Analytics at Royal Holloway. New methods to detect motion, track objects and classify behaviour in CCTV now enable the efficient scanning of video for important events. Kinesense Ltd has developed a range of forensic video analysis tools, which reduce the time required to search and analyse video footage by up to 95%. It has attracted investment funding of over €820,000, employs 7 full time staff and has made sales to police forces and security agencies in over 17 countries. Kinesense products benefit law enforcement professionals and organisations by providing more efficient surveillance and detection of criminal activity, allowing better use of investigator time, reducing the length of criminal investigations and increasing their success rate. The general public worldwide benefits from increased crime detection and the consequent prevention and reduction of criminal activity.
The introduction of computer vision algorithms that allow creation of stereo 3D content in film and broadcast using conventional 2D monocular video cameras has permitted fundamental advances in the 3D reconstruction of complex real-world dynamic scenes from video, enabling the rendering of stereo views from a single camera view. Technology introduced by Surrey has been used for 3D scene analysis by the UK company, The Foundry, in their film post-production for major Hollywood 3D film productions (Avatar, Harry Potter, Planet of the Apes, Tron, The Hobbit). Since 2007, The Foundry has transformed to become the leading provider of 3D stereo production software tools to the global visual effects industry, growing from 20 to over 200 employees.
In the late 1990s, a significant barrier to the adoption of virtual reality software was the expense of manually creating models of real-world scenes. To address this, between 1998 and 2004, the ICARUS software system was developed, which enabled the creation of structured, 3D geometric models from a sequence of images or video. The system also pioneered improved methods of camera tracking. ICARUS was subsequently licensed and developed commercially, and became the foundation for video and film post-production products that are used worldwide in the film (e.g. Universal Pictures, Warner Bros, Paramount Pictures) and television (e.g. BBC) industries, underpinning a company with an annual turnover in excess of £1m.
UCL's research has led to changes in patient care for men with prostate cancer, through the implementation of less invasive, image-directed treatment and diagnostic strategies, and clinical trials that use these techniques. The use of medical image registration software to deliver high- intensity ultrasound therapy in a targeted manner has been shown to change the treatment plan in half of the patients participating in a clinical study. New biopsy criteria are now used routinely to classify patient risk at University College Hospital, where, since 2009, clinicians have determined the treatment options for more than 741 prostate cancer patients. The scheme has been adopted, by 15 other hospitals in the UK and internationally, where it has become the recommended standard of care, and has been used to treat more than 1,200 patients.
Video surveillance or monitoring is an important ingredient of modern life. Research conducted by the 2017Centre for Information, Intelligence and Security Systems` (CIISS), into improving the reliability of automated detection of visual entities in videos, has made an impact on public services and on practitioners (increased speed and quality, lower labour cost — Beneficiaries: U.K. Police; police investigators) and their health (mitigation of potential physical or psychological harm — Beneficiaries: police investigators), on society (reduction of a factor associated with crime rates and legal costs — Beneficiaries: the public; tax-payers), and on business (creation of a spin-out company - Adaptive Video Analytics Technologies Ltd — Beneficiaries: UK; and influence on management decisions about technology choices — Beneficiaries: Serco Group plc (HMP Dovegate)).
